Cycling Weekly Verdict

The Polar Vantage V2 is packed with features that will satisfy anyone wanting to track their progress and improve performances. But while it is easy to navigate and offers a wealth of generalised – and customised – advice, it does lack some features other watches boast at this price point. The lack of onboard music and comprehensive mapping are most notable for their absence. Whilst it will likely be a hit with long-standing Polar fans, it simply doesn't out-perform the competition.

The Polar Vantage V2 is a great smartwatch for any athlete taking training and competition seriously. With comprehensive testing for runners and cyclists, recovery and nutrition monitoring, and a broad range of widgets to rival most smart watches, there is a whole lot going on underneath the hood.

That said, in comparison to some similarly priced alternatives, you could be left feeling short changed in certain areas. Music, mapping and some minor issues with syncing work are all niggles that don't help its case.

What's in the box

The watch body is made from an aerospace aluminium alloy combined with a glass-fibre reinforced polymer. Its 47mm diameter face features a laminated Gorilla glass lens with an anti-fingerprint coating and while the proprietary silicone strap isn’t as flexible as some silicone straps, but is comfortable enough and is certainly robust.

There are two size options for the strap: small, to fit wrist circumference of 120-190mm and medium to wrist circumference of 145-215mm. The red version that I've been testing is among the bolder colours, but there are other options, including a black body with a black strap, a black body with a military green strap, or a grey body with a grey-lime strap.

The V2 comes with a custom, 800mm long, USB cable for charging and data synchronisation.

As I've been testing the basic package, I haven't been able to explore quite all the features on offer. A bundle with a H10 heart rate strap costs an extra £40 – money well-spent in my opinion for any keen cyclist or runner. There is also a bike mount available for the watch, but this is an extra accessory and not available in a bundle. 

Charging and battery life

The V2 goes from flat to full in 100 minutes. This is pretty decent, though not as good as some; Garmin’s Forerunner 945 would consistently go from flat to full in 75 minutes. Like all comparable watches, run time depends on what you ask of it. I had the Forerunner 945 and Vantage V2 running simultaneously for a few weeks to enable direct comparisons. 

With an identical regime of at least one activity per day and continual use otherwise, plus general interaction for notifications etc, the V2 ran for 126 hours before flashing up a 10% warning. At this battery capacity, the watch will not record an activity and it died 7 hours later. 

By comparison, the Garmin continued to function on every level until its bitter end and lasted 66 hours more than the Vantage V2. However, the V2 does have power saving modes to extend its battery life further and I have been finding these effective.

The battery capacity is clearly displayed on the screen as a percentage and if it is in need of charging, the app will remind you when you sync it by way of an orange battery warning appearing at the end of the sync.


In addition to the V2’s touch screen, there are five buttons to navigate the faces and menus, each triggering a short vibration when pressed. I like this feature; in the heat of a training session, a vibration to confirm a pause or stop is helpful. The touch screen isn’t the most refined; there's a very slight lag, but nothing that would personally put me off buying the watch. I’ve frequently noted that the screen has changed, or I’ve entered data field without intentionally touching it. Thankfully, it’s automatically disabled during an activity; you rely on the buttons for navigating then.

A variety of (digital and analogue) watch faces can be customized to tell you much more than just the time and date. Metrics that can be added include: daily activity, cardio load status, continuous HR tracking, latest training sessions, last night's sleep, FitSpark training guide, weather, weekly summary, music controls and sunrise/sunset. Tapping on any one of these screens gives you greater detail.

A FitSpark feature suggests daily workouts to maintain your current fitness level. They include strength, cardio, and supportive (typically flexibility-focused). Below, you can see a core workout, each of the figures are animated to aid interpretation of the suggested exercise. 

You will never be short of metrics from any one of the faces, though understanding how they are all calculated is worth taking time to familiarise youreself with. For example, the Cardio Load Status looks at the relation between your short term training load (Strain) and long term training load (Tolerance) and, based on that, tells you whether you are in a de-training, maintaining, productive or over-reaching training load status. When recovery tracking (via Recovery Pro, which requires the chest strap) is set 'on' and enough data is available, you'll see your daily training recommendation instead of your cardio load status on the watch face. 

The Nightly Recharge status tells you how restorative your last night was. Nightly Recharge combines information on how well your autonomic nervous system (ANS) calmed down during the early hours of your sleep (ANS charge) and how well you slept (sleep charge). You get a plethora of metrics about your last sleep, as well as averages over a week. This is accessible on the watch, as well as in the app. 

The sleep tracking was a bit hit and miss; at times it had me sleeping when I was in bed reading. On the whole it tallied with how I felt I'd slept, though there were often significantly different recordings of sleep quality and quantity when compared to the same night with the Garmin Forerunner 945. I would never rely on any smart watch to provide 100% accurate data here. That said, they are a decent source of information to help prevent over-training and sickness. Interestingly, you can edit the (start and end of a) sleep profile in the app.

For many, the sheer number of options will be overwhelming. Over the first few weeks of use, as you become familiar with the watch, you'll find yourself swiping straight past of some of them, or relying on the app for others. It's easy to deselect those that you aren't making use of via the settings on the watch itself. For me, changing settings on the watch was more intuitive than on the app.

Polar Flow app

All data is synced to the Polar Flow app and available to view there. While it's not difficult to navigate, it's not always as intuitive as it could be. On top of this, I personally didn't find all the graphs easy to interpret; some lack labelling and units. 

Syncing has to be done manually. I initially set up everything on an iPhone. This was not arduous or lengthy; the device was paired in no time and I had it linked to Strava, Training Peaks and Komoot without issue. Occasionally I would have an issue where it would simply fail to sync on the first or second time of asking, but repeating the process would eventually get it to do so.

I did miss the automatic syncing present in Garmin devices – no button press post-workout, just an automatic upload and transfer.

Reviews on the app store of Polar Flow are very contrasting. Out of curiosity, I switched to using the app on Android. I lasted about 24 hours; it was terribly hit and miss. It's worth saying that my Android is more than 5 years old, so may not be a reliable judge of the apps performance.

There are some decent in-app features worth mentioning. A blog with regular, relevant articles and a direct link to feature tutorials are both nice additions. Views are customisable and sessions are easy to add to your diary manually.

Getting sporty

There’s a massive range of indoor and outdoor activities available via the Polar Flow app, the watch can hold up to 20 different profiles at any one time. Common ones such as road cycling, indoor cycling, mountain biking and spinning, plus road, trail, treadmill and track running are listed among more obscure ones. There are well over 130 available.

Each profile is customisable within the app, allowing up to 8 pages of metrics, each arranged to suit your personal preference. Frequency of updates, zones (pace, power, and heart rate) and automatic laps can be set too. All of the changes will be implemented when you sync the watch.

Before starting a session, after entering the profile, the watch will tell you how many hours of recording are available for that activity (with GPS). Here, I've entered a cycling profile (just after charging the watch), there's up to 33 hours of recording available. 

The watch is searching for GPS signal and doesn't have a heart rate signal. When signals are detected, the icons rings go green and the heart rate begins to show.

The watch face is easy enough to read, but for me, it doesn’t have the contrast of the Forerunner 945 conducive to easy reading when exercising. The on-board sensors were sluggish at times too. Certainly while warming up, the heart rate lagged behind a chest strap sensor and the 945 optical sensor (on the other wrist). 

If I started an interval, the Polar took some time to register a change in heart rate. This is frustrating for analysis; time spent in a higher zone is not being recorded. Speed was more reliable, though under cover of trees, signal could be patchy.

The V2 supports most Bluetooth Smart sensors: heart rate straps, cycling power meters, cycling cadence & speed sensors, running footpods, running power meters (it includes a built-in one too) . For cyclists, Polar has a list of guaranteed power meters, though it’s far less extensive than competitors and there’s no support for ANT+.

It’s possible to pair multiple types of sensors to the watch (via the sensors menu) and, in turn, effectively save multiple bikes’ sensor configurations, heart rate straps or any other desired sensor.

Notable features for cyclists and runners include duration customised FTP tests (requiring a power meter) , Running Performance Testing and a linked
