Coros Vertix 2S Assessment – iRunFar

This spring, Coros launched an addition to its flagship watch collection with the Coros Vertix 2S ($700). After the unique Coros Vertix, then the Coros Vertix 2, why is Coros calling this replace “2S” as an alternative of Vertix 3? It has to do with the truth that it’s not a completely new watch; it’s extra of an improve of particular components (just like the optical coronary heart fee sensor) and new GPS system algorithms, that are alleged to have an effect on sport-specific GPS accuracy (like for multi-pitch rock climbs.)

Coros additionally made some vital modifications aesthetically, with its three kinds adopting a “area,” “moon,” and “Earth” aesthetic, with darkish colour straps and background screens. The price of the improved antenna and higher optical coronary heart fee sensor implies that general battery life is definitely barely worse than its predecessor, the Vertix 2, when utilizing both normal and “all techniques on” GPS modes.

After we initially reviewed the Vertix 2, we acknowledged that, even amongst Coros’ different watch choices, the Vertix collection might not be the most suitable choice for pure runners.

Coros’s personal advertising means that the Vertix 2S, similar to its predecessors, is an “journey” watch, meant to be used in massive mountains in all circumstances. The watch makes use of sapphire glass and a titanium bezel that shouldn’t break below any sporting utilization.

The watch’s unbelievable battery life will make it tempting for ultrarunners, since it should final for so long as almost any of us would possibly contemplate operating. Within the matrix of Coros’s ambassadors, there are rock climbers like Tommy Caldwell on one finish, Kilian Jornet within the center, after which Sally McRae, who notably has change into a fixture of the 200-mile race scene, who’re every utilizing the Vertix 2S — versus the Coros Apex or Coros Tempo watches — seemingly for the sheer battery requirement of every particular person’s endeavors.

There’s a trove of information to be mined from actions, in addition to throughout relaxation, so it’s no surprise the notoriously analytical Jornet is at house with Coros tools.

Within the final 12 months, Suunto has launched a few watches that give a lot stiffer competitors than prior to now to Coros’s “finest battery life” claims, and Garmin continues to be the usual bearer in relation to the mixture of battery and options.

The Vertix 2S continues to make use of of a pair issues I discover annoying about Coros watches, chief amongst them its digital dial and the extraordinarily twitchy response to pushing its buttons or utilizing the touchscreen. The complaints are minimal, so hold studying to search out out about extra updates within the Vertix 2S, its efficiency and options and what, if the rest, has modified from the Vertix 2.

A be aware on sure examples and context: this evaluation incorporates a number of the similar materials and examples we used for our long-term check of the Vertix 2. Because the Vertix 2 and Vertix 2S share almost the very same {hardware} and software program, the remarks in regards to the Vertix 2 are nonetheless applicable, significantly in relation to particular race-oriented testing, significantly attributed to iRunFar’s Meghan Hicks.

The Coros Vertix 2S is one among a number of glorious GPS watches in the marketplace, so make sure you additionally verify our information to the Greatest GPS Working Watches to see how we examine the Coros Vertix 2S with different prime watches.

Coros Vertix 2S Dimension and Weight

The Coros Vertix 2S really has the very same display screen measurement (1.4”) because the Vertix 2, however is now two grams lighter at 87 grams. The general bundle is in any other case the very same because the Vertix 2 — like that watch, the Vertix 2S comes with two straps — one silicone, one nylon.

In our testing, the nylon strap proved to be invaluable when attempting to get essentially the most accuracy out of the optical coronary heart fee sensor, whereas minimizing discomfort in your wrist (extra on that within the optical coronary heart fee part beneath.)

This huge measurement and mass are partially defined by merely needing area to accommodate the options of a big battery and a souped-up processor.

The opposite doubtless motive the show is so giant is to permit customers to show lots of knowledge concurrently. You possibly can show eight knowledge factors all at one time on the display screen, which is fairly cool — in case your eyesight is sweet sufficient to learn them whereas on the transfer. One more reason Coros might need leaned into measurement with the Vertix 2 and Vertix 2S is to permit customers to higher navigate a map on the display screen. The watch consists of on-board, pre-loaded maps, and there are extra you’ll be able to obtain from the Coros web site. A brand new extender characteristic permits your telephone to reflect the map in your watch. We focus on this characteristic extra in depth beneath.

You use the watch utilizing one among its three dials, in addition to its touchscreen, the latter of which works with just some options.

Coros Vertix 2S Look and Really feel

Coros was excited to announce the brand new look of the Coros Vertix 2S, they usually designed three totally different kinds impressed by Earth, area, and moon. Our check watch got here within the area design, with its rugged grey colour scheme and outer area background.

It is a a lot cleaner search for Coros, however the usability really decreases. Though prettier than Coros’s typical Android-looking UI, the small font is tougher to learn and the optionally available knowledge factors that may be displayed (like steps, elevation, coronary heart fee, dawn) don’t have sufficient distinction to interpret rapidly. This default area theme might be changed wholesale by altering the show within the watch face menu, turning the watch face into conventional, daring Coros designs.

Just like the Vertix 2, the Vertix 2S retains its very rugged-looking kind, from its burly bezel and dials to the tough-looking silicone band. It appears like you could possibly actually run it by a wringer with out difficulty. With out the loud orange silicone strap of its predecessor, the Vertix 2S’s pretty grey colour means it received’t draw as a lot consideration, or sign “sports activities watch” once you’re carrying it in non-outdoor conditions, like at work.

Like Garmin watches, this watch helps you to select between quite a few totally different display screen kinds, which provide a variety of fonts, sizes, and colours. These display screen kinds additionally heart squarely in a rugged aesthetic.

Whereas a few our testers favored the appear and feel of the Coros Vertix 2S, one didn’t. We’ll simply put it on the market — should you’re searching for clear traces or a sense of sophistication by minimalism, you received’t discover it on this watch. For those who change to the optionally available nylon band, the watch does shrink in measurement and tackle a barely much less burly look. The monochromatic grey straps with the all-gray Vertix 2S unit is fashionable and extra subdued than its Vertix 2 predecessor.

However it’s nonetheless lots sufficient watch to assemble the commentary from of us about its measurement. In our opinion, Suunto watches have the cleanest, most refined aesthetic of GPS operating watches in the marketplace immediately.

Dimension nonetheless issues although. The watch’s footprint isn’t just an issue of aesthetics, says two of our three testers. One member of the iRunFar check staff notes that the watch is so massive they generally wrestle to get it by the wrist holes on tight operating shirts or by the sleeves of additional layers, significantly whereas operating.

Adjustability and convertibility are improved with the Vertix 2S, in comparison with the competitors. One instance is Coros’s nylon strap design — it’s mounted to 1 finish with a hook and loop to loosen and tighten on the opposite. This design is definitely rather a lot higher than Garmin’s tackle the nylon strap; theirs isn’t mounted on both finish so you must modify both sides to make it match. The Vertix 2S is less complicated to get on and off, in addition to to dial in a cushty match, in comparison with Garmin.

Utilizing the Vertix 2S throughout non-running actions, resembling mountaineering or Nordic snowboarding, with frequent flexion on the wrist, leads to often hitting the crown inflicting the watch to cease or begin recording unintentionally. We examined the watch on our left wrist and the big dial sits proper the place the bones are on the wrist. If this turns into a difficulty for you, you’ll be able to allow an auto-lock characteristic that stops you from by accident pausing the watch, however it’s an additional step.

Additionally of be aware, within the settings, Coros prompts you to pick on which wrist you’ll put on your Vertix 2S in order that the interface flips to accommodate your selection.

The Coros Vertix 2S collects quite a few biometric knowledge factors that can assist you observe your well being and well-being exterior of your coaching, which we’ll discuss in larger depth beneath. So, you must be keen to put on this huge watch on a regular basis to make full use of its options.

Coros Vertix 2S Battery Life

For path operating and ultrarunning, battery life is arguably essentially the most prized characteristic. All GPS watch manufacturers in and across the Coros Vertix 2S’s worth level have significantly stepped up their battery efficiency over the past two years. Some have targeted on offering distinctive options along with excellent battery life, whereas Coros has targeted on offering one of the best battery life, nearly to a fault.

Coros has positioned the Vertix 2S the identical method it positions all of its watches: distinctive, just about class-leading battery life. To their credit score, Coros has an superior comparability perform on their web site, the place you’ll be able to rapidly see a number of watches spec’ed in opposition to one another.

Utilizing this perform revealed that the Vertix 2S really has barely poorer battery efficiency general in comparison with the Vertix 2: 118 hours (9 hours lower than the Vertix 2 in normal GPS mode) and 73 hours in “all techniques on” mode (15 hours lower than the Vertix 2.) “All techniques on” implies that 5 of the main satellite tv for pc techniques are pinged concurrently: GPS, GLONASS, Galileo, Beidou, QZSS.

The battery drawdown is coming from the extra energy-intensive and extra correct optical coronary heart fee sensor, but when coronary heart fee monitoring isn’t that vital to you, you’ll be able to decrease this perform by selecting to document coronary heart fee constantly or simply each ten minutes. You can’t, nonetheless, flip it off totally (besides throughout exercise modes).

Each the Vertix 2S and Vertix 2 are large enhancements over the unique Vertix, with round double the battery lifetime of the unique.

With regards to charging the watch, that too is extremely quick. Coros claims it takes two hours to cost from zero to 100%. As a result of it’s nearly not possible to empty this monumental battery, we’ve not been capable of corroborate this declare. What’s extra regular for our check staff is to cost the battery each couple of weeks, after about 25 to 30 hours of operating.

On this case, the battery sits at about 30% capability, and charging to full takes about 75 minutes. It expenses quick, sufficient mentioned.

For ultrarunners searching for the comfort of just about by no means having to cost their watch, the Vertix 2S is likely one of the finest choices presently obtainable. Once you’re not doing actually lengthy runs or races, you could possibly use the look ahead to an hour in regular GPS mode just about daily for a month while not having to cost.

Some options just like the electrocardiogram, the Insta360 digicam management, and enjoying music add some drain to the battery, however general, the Vertix 2S manages to maintain unbelievable efficiency regardless of these added calls for.

The Vertix 2 and Vertix 2S use a proprietary charger, so make sure you retailer it safely.

iRunFar’s Meghan Hicks examined the Coros Vertix 2’s battery life at its highest settings, the place the watch connects to 5 totally different satellite tv for pc techniques (GPS, GLONASS, Galileo, QZSS, and BeiDou) in twin frequency, through the 126-mile Snowman Race stage race in Bhutan. This amounted to competing for 51 hours over 5 days within the high-altitude Himalayan wilderness. Coros claims the battery would final for 50 hours at this setting.

Meghan ended up charging the watch on the fourth and remaining night time of tenting, after 43.5 hours of use over 3.5 days out, forward of the final, fifth stage, utilizing a conveyable battery charger. Meghan says there was most likely sufficient battery energy to not want a recharge, however she didn’t dare tempt destiny to expire of battery within the final miles of the occasion. The Vertix 2 at the very least matched this battery life declare.

Coros Vertix 2S Processing Pace

Whereas all Coros watches have nice processing pace, the Coros Vertix 2S maintains the 20% sooner pace launched within the Coros Vertix 2, a characteristic the iRunFar staff beloved. From how briskly the watch scrolls between screens and sport modes, in addition to how briskly it reacts to button picks, it’s clear that the Vertix 2S is utilizing a superior chip in comparison with Garmin, and particularly Suunto.

I used the phrase twitchy to explain the processor within the introduction, and let me broaden on that. My day by day driver — and favourite GPS watch up to now — is the Garmin Enduro 2. Its processing pace is completely satisfactory, and I’m very used to it from day by day use. The Vertix 2S by comparability strikes a lot sooner, to the purpose of inadvertent or unintentional button picks.

Whereas it’s unbelievable to maneuver across the watch’s options and capabilities so rapidly — it actually does set the usual for usability — it could be good if there was an choice to lower the sensitivity by 1 / 4 or half pace.

One space the place the processing pace positively impacts the consumer expertise is in mapping mode. It’s implausible at zooming and transferring across the panorama. You’ll additionally discover the pace when clicking between screens or choosing totally different watch capabilities, which you’ll see is very quick in case you are acquainted with comparable actions with different watches.

A remaining be aware about processing pace — sadly, a sooner chipset doesn’t affect GPS sign acquisition. That is nonetheless satellite-reception-dependent, so even a super-fast watch will nonetheless take the identical period of time to accumulate positioning as different GPS watches in the marketplace.

Coros Vertix 2S Extra Options

Right here we’ll take a look at just a few extra options of the Coros Vertix 2S.

Maps and Navigation

In an enormous enchancment from the unique Vertix, navigation options with panorama, topographic, and hybrid world mapping might be accessed within the Coros Vertix 2S. In a serious improve from the Vertix and Vertix 2, Coros now has in-app performance the place you’ll be able to construct a route instantly; it is rather simple to make use of and syncs with the watch in a couple of second.

In contrast to in competitor Garmin watches, when navigating a route or just scrolling round an space on the maps within the Vertix 2S, there are not any labels, names, or turn-by-turn navigation. This gives a typically clear look that means that you can see your observe and the fundamental options of the world round you and to do very primary navigation actions, resembling following alongside as your route strikes amongst vital terrain options or turning from one path to a different.

Nonetheless, you wouldn’t need to use the look ahead to detailed navigation wants. Journey runner sorts needs to be utilizing paper maps and mapping apps on their bigger telephone screens to do their detailed navigation anyway.

Mapping is the one touchscreen-enabled characteristic that’s significant on the Vertix 2S. You too can use the dial on the aspect of the watch to zoom out and in of the maps. Each methods of utilizing mapping should not solely nifty, but in addition almost instantaneous, which we beforehand wrote about in reference to the Vertix 2S’s processing pace.

Of their April 2024 over-the-air or firmware options replace, Coros introduced a brand new extender characteristic for outside actions. The extender means that you can populate a real-time map in your telephone, mirroring the information being collected on the Vertix 2S in your wrist. From a navigation perspective, this provides you two benefits: first you get a a lot greater map show in your telephone display screen with the power to decide on between three totally different map sorts, and secondly, you’ll be able to navigate landmarks far more simply as a result of your telephone now has labels, the place the conventional watch mapping doesn’t.

A helpful characteristic that has carried over from the Vertix 2 to the Vertix 2S is the navigation error alert characteristic. In a nod to the wild and rugged terrain the Vertix collection is constructed for, iRunFar’s Meghan Hicks additionally used the Coros Vertix 2’s mapping and navigation options through the Snowman Race in Bhutan.

Whereas the race had excellent course markings, it traveled trails created by locals and their horses and yaks to hold provides out and in of Bhutan’s distant Himalayan villages. Purposeful livestock trails are very totally different from human-constructed, Western trails, in that they change into braided by way of livestock’s pure actions in numerous instructions on the path. Meghan relied on the navigation alert to be warned that she was off-route by a bit of bit, in addition to the mapping characteristic, which allowed her to rapidly zoom in and across the map to see the place she was in relation to the race course.

Typically, Meghan would thusly discover herself on a trail-braid and away from the Snowman Race markings. Moreover, the course was enveloped by thick fog one late afternoon and into the night time, which made seeing the course markings tough.

All of this mentioned, iRunFar feels strongly that the Coros Vertix 2S — or any GPS operating watch — shouldn’t be a major or solely navigation instrument. The watch display screen of any watch is simply too small to get the assorted views it is advisable navigate, and the maps should not detailed sufficient to navigate correctly.

It is best to all the time depend on a path system’s provided map indicators, a paper map, or mapping apps in your telephone for protected navigation. As a substitute, contemplate the mapping and navigation applied sciences of your GPS watch as a instrument that can assist you make fast and straightforward navigation choices and course corrections on the transfer.

Music Storage and Entry

Just like the Vertix 2, the Coros Vertix 2S technically has music and podcast capabilities, that means it should play again information utilizing its inner storage. Coros nonetheless hasn’t added syncing capabilities with offline playlists on Amazon, Spotify, or Apple Music to the Vertix 2S, so that you’ll have to purchase or in any other case supply music information, obtain them, after which drag them over to the watch’s storage on your property pc. It’s simple to do, however considerably gradual to switch. To hear, it’s essential to pair Bluetooth wi-fi headphones.

I respect watches that may play music, as I actually don’t like operating with a telephone, however once more — not like the Garmin fēnix or Enduro watches, which may sync with playlists from widespread streaming companies — you’re restricted to manually transferring MP3 information as you used to in your iPod years in the past. It is a very unmodern resolution, however it’s higher than not having any music choices.

Coros Vertix 2S GPS Accuracy

Within the class of GPS accuracy, the Coros Vertix 2 debuted a first-of-its-kind on the GPS watch marketplace for providing twin frequency GNSS. This spectacular characteristic, replicated within the Coros Vertix 2S, permits the watch to find one of the best GPS frequency obtainable from all 5 of the main satellite tv for pc techniques — GPS, GLONASS, Galileo, QZSS, and BeiDou — concurrently.

This, in concept, ought to supply large accuracy enhancements over earlier GPS models, however throughout our testing, it carried out fairly equally to the opposite watches in our information to the Greatest GPS Working Watches.

There may be one state of affairs the place we’ve skilled elevated GPS accuracy of the Coros system over that of Suunto: transferring by a canyon with tight rock partitions rising up round us.

One member of the iRunFar check staff usually does speedwork on a paved highway by a canyon. And, of their earlier use of a number of Suunto watch fashions on this location, they discovered the watch indifferent from the GPS system sufficient that they as an alternative wanted to make use of highway indicators and a timer to measure progress somewhat than GPS knowledge. This has modified with the Coros Vertix 2 and Vertix 2S in the identical location, as they’ll depend on the watch to supply correct, live-time readouts of tempo and distance whereas transferring quick.

Although it’s not a running-specific replace, the Vertix 2S touts a brand new algorithm for improved accuracy for multi-pitch mountaineering. Even with the dual-frequency band enabled, monitoring mountaineering has been very tough with any GPS watch I’ve used — assume extremely squiggly and criss-crossed traces throughout your exercise — due to the steepness of partitions and the restricted distance to clear skies.

Although on paper this replace could be implausible, I used the outside climb mode the place this improved accuracy was alleged to take form, and located it sadly produced no higher observe than I’ve gotten on my Suunto or Garmin watches whereas climbing. Happily, Coros is dogged in relation to tweaks and enhancements in GPS accuracy, so we count on to see this resolved or improved sooner or later by way of firmware updates.

Coros Vertix 2S Optical Coronary heart Price Sensor and Coros Updates

One of the thrilling updates with the Coros Vertix 2S in comparison with the Vertix 2, is the advance within the optical coronary heart fee sensor. Whereas it’s a brand new and improved sensor, there are additionally algorithms at play that assist complement the accuracy of the sensor. For instance, Coros often updates the algorithms to help totally different sports activities and the distinctive actions inherent in every.

So, for instance, the ”path operating” and “operating” sport modes will use barely totally different algorithms to account for the totally different actions and motions you would possibly make use of when on an undulating path versus a predictable highway. The sensor is improved, however it additionally actually issues the way you put on the watch to get one of the best readings.

Sporting the Coros coronary heart fee strap paired to my Enduro 2 on one wrist and my Vertix 2S on the opposite, I in contrast the guts fee output on a number of events, together with a race-pace effort on a ten-mile run. The info from each units was shockingly comparable throughout these checks; it’s an actual testomony to the enhancements in Coros’s {hardware}.

The one disadvantage is it may be uncomfortable and exhausting to maintain the watch about an inch (Coros says it want solely be one centimeter, however I discovered it to be greater than that) larger up your wrist than you’d generally put on it. Many instances whereas operating, and looking for the sensor’s candy spot, the readings would present my coronary heart fee at unfathomably excessive numbers for the extent of exertion, or cadence locked constantly on a a lot larger quantity than the exertion I used to be placing forth.

There are just a few tricks to getting one of the best optical coronary heart fee knowledge assortment, in response to Coros Head of Person Engagement, Darian Allberry. His three guidelines of thumb are:

1. Put on the watch tight and better above the wrist bone.
2. Guarantee firmware is updated and choose the proper exercise profile, i.e.: Run vs. Path Run — this vital distinction evidently accounts for the extra jostling you would possibly expertise whereas path versus highway operating.
3. Swap wrists, as some watches, for no matter motive — anatomy or in any other case — will carry out higher for various our bodies with seemingly no rhyme or motive.

These primary tips might be utilized to any producer’s gadget, whether or not or not it’s Coros, Suunto, Garmin, or Apple Watch, and so forth.

Admittedly, this comes at a time when Coros lately launched its personal coronary heart fee strap — maybe this was supposed as a complement to present Coros watches that haven’t been up to date to the identical sensor because the Vertix 2S — it can be seen as an admission that optical coronary heart fee seize remains to be in want of an enormous enchancment.

Regardless of the problem, Coros maintains its enthusiasm and dedication to enhancing the optical tech in order that the quite a few metrics that depend on coronary heart fee — HRV, sleep rating, restoration, readiness, coaching load, and oxygen saturation to point illness — are captured and used to create a full image of the runner.

It will be good sooner or later sooner or later if optical coronary heart seize was absolutely and reliably “set it, neglect it,” however frankly it nonetheless shouldn’t be. Solely when carrying the watch unusually excessive in your wrist is the sensor capable of seize dependable knowledge. That is the place the optionally available nylon strap is very helpful. It’s method too uncomfortable to put on the stiffer silicone band with its pre-set adjustment notches this excessive up on the arm, whereas the nylon strap at the very least means that you can dial in a extra exact slot in a extra snug materials.

Coros Vertix 2S Updates and Exterior Options

The Coros Vertix 2S advantages from quite a few updates that Coros bundles roughly each quarter or so by their replace bulletins.

Because the Vertix 2 was launched in 2021, there have been numerous enhancements and add-ons that make the Vertix 2S extra feature-rich. Observe that these updates work nearly universally throughout older watches, not simply on the brand new Vertix 2S, and might deliver an older watch as much as most trendy software program variations.

These enhancements vary from algorithm updates, such because the above-noted GPS enhancements for mountaineering GPS accuracy, to a Wellness Test, which mixes blood oxygen saturation, HRV, sleep, and operating fatigue in a quite simple and easy-to-read image within the Coros app.

Coros additionally gives a free teaching instrument by means of the Coros Coaching Hub. Whereas it’s free to put in and use, it requires the assistance of a coach to prescribe coaching, though Coros additionally gives free help by its community of coaches, permitting Coros customers to get solutions to questions on coaching instantly from its staff.

Coros Vertix 2S Total Impressions

In our opinion, the Coros Vertix 2S is a prime contender for path runners and ultrarunners who have a tendency towards lengthy outings in wild locations.

The place this watch shines the brightest is on multiday or lengthy, nonstop outings the place you will have a protracted distance to cowl earlier than you’ll be able to or need to recharge the battery.

iRunFar’s Meghan Hicks used the Vertix 2 with its all techniques on GPS setting through the five-day, 126-mile Snowman Race stage race, which took her 51 hours to finish over 4.5 days within the wilderness. She solely recharged it on the fourth and remaining night time of tenting earlier than the final, fifth stage. Meghan admits there was most likely sufficient battery energy to not want a recharge, however she wished to make sure that it could take her all the way in which to the end line.

To deal with an analogous endeavor with the Vertix 2S, please pay attention to the slight discount in battery energy, an unavoidable byproduct of the brand new optical coronary heart fee sensor.

For those who’re an individual who can’t be bothered to recharge your watch each few days, and also you’d like to only set it and neglect it — for weeks at a time — the Coros Vertix 2S is a good choice.

Followers of health and biometric monitoring will even be capable to depend on the Vertix 2S to cowl most every part their Fitbit or comparable tracker already data; the app will relay a formidable quantity of non-running efficiency and well being indicators.

The Coros Vertix 2S is an enormous, heavy watch, which some will like, and a few received’t, however with its extra refined colours and bands, the watch received’t scream “sports activities!” like earlier Vertix fashions did.

There’s a lot to love in regards to the Vertix 2S past battery life, however it’s debatable whether or not this watch, with its gigantic show and equally giant price ticket, would be the best option for most individuals who simply run.

And this isn’t a knock in opposition to Coros; in reality, their Tempo collection is one of the best GPS watch in the marketplace immediately once you need a easy watch for normal operating. It’s that the Vertix 2S doesn’t do what another inexpensive watches do for much less cash.

In closing, should you’re a path runner or an ultrarunner who loves super-long, adventurous runs — otherwise you’re somebody who doesn’t need to cost your GPS operating watch each few days — the Coros Vertix 2S could possibly be the proper look ahead to you.
