Henry Cavill's favorite Polar running watches have up to a third off for Black Friday and Cyber Monday

Polar Vantage V2 running watch: was $499.95 now $399.95 at Polar
Save $100 on the Polar Vantage V2. The V2 is Polar’s premium running offering, with an accurate heart rate monitor that can calculate running power on the wrist alone. Garmin and other brands require a separate heart rate monitor to calculate this metric. It lasts up to 100 hours with full GPS usage, and it supports multiple satellite systems including GPS, GLONASS, Galileo, and QZSS for pinpoint-accurate tracking. 

Polar Grit X Pro adventure watch: was $499.95 now $449.95 at Polar
Save $50 on Polar’s awesome adventure watch. The Grit X Pro boasts four stars in our review, using Polar’s GPS smarts to facilitate adventuring. It’s tough, with a sapphire glass and polymer build, and it has the Polar Precision Prime heart rate monitoring tech that makes the Vantage V2 sing. An excellent Garmin rival. 

Polar Vantage M2 running watch: was $299.95 now $200.97 at Polar
Almost the same discount as the Polar Vantage V2, but it’s a greater proportion of the full price of Polar’s mid-range entry, making it a better deal overall. Get most of the Vantage V2’s smarts in a smaller package, with up to 40 hours of training on a single charge rather than 100 and it’s only water-resistant to 30 metres. But that's still more than enough for most people’s needs, at half the price of the V2. Ideal for half-marathon runners. 

Polar H10 heart rate monitor: was $89.95 now $71.96 at Polar
When it comes to pinpoint-accurate heart rate measuring, the H10 is what you need. More accurate than the estimations from most wrist-based watches, the H10 is perfect for serious runners and riders looking to get the most accurate measurements they can. Now save almost $20 on the total price.  

Polar H9 heart rate monitor: was $59.95 now $47.95 at Polar
Polar’s older HRM isn’t dead tech: it packs 400 hours of battery life, Bluetooth and ANT+ connections. It’s not lauded as the ‘gold standard’ of heart rate monitoring as the H10 has superceded it, but there’s plenty to like here and it’s $24 cheaper than the H10. 

Polar Vantage V2 running watch: was £429.00 now £343.00 at Polar
Polar’s premium racing watch is also down in the UK, with £76 off the watch to bring it under £350 - an attractive prospect. If you’re a runner looking for a fitness watch to really level up your performance, Polar’s range of detailed running metrics rivals any of its contemporaries. 

Polar Ignite 2 running watch: was £199.50 now £155.61 at Polar
This is a great buy for someone graduating from 5Ks into longer running and wants to up their game. This little watch provides lots of the metrics and accurate heart rate monitoring of its bigger siblings but in a smaller, cheaper package. A bargain for £155 if you’re a runner and worth picking up over one of the new Fitbits.  

Polar Grit X adventure watch: was £369.00 now £258.30 at Polar
Save over £100 on the Polar Grit X watch, a good adventure companion with great GPS credentials. Normally, we’d recommend picking up a Garmin over the Grit X at full price, but for around £250, weekend warriors will find it tough to choose.
