Benefit from Coros technologies

Coros watches and technologies are already trusted by world-class athletes such as Eliud Kipchoge, record holder and double Olympic marathon champion and Kilian Jornet, trail and ultra-trail champion!

Also take advantage of its many features that allow you to follow you performance from the APP. Available on iOS and Android. Please note that the product cannot connect to a computer to interface, but only to display the data.

Enjoy your watch's long battery life

Your watch has a battery life of 35 hours in GPS mode and up to 80 hours in Ultramax mode (30 seconds of recording every 120 seconds). In everyday use, it can last up to 30 days. With intensive everyday use (backlighting at the wrist, sleep tracking and frequent notifications), you can expect about 20 days of battery life. Note that it takes 2 hours to fully charge the watch with the charging cable that comes with the watch (and is also sold separately).

Swim with the product

The watch can be worn while swimming at the surface thanks to its 5ATM water resistance. The heart rate sensor also works under water!

Connect your sensors

Quickly detects the GPS signal

3 modes available to ensure optimal signal detection: GPS+BDS+QZSS/GPS+Glonass+QZSS

According to my needs it's definitely an amazing value to money. The app, the watch, the customisation, settings, battery span, all are absolutely great.

Best sub £200 on the market!

Upgraded from a Garmin 45plus. Battery life is brilliant and as advertised. The quality is good, with a larger wheel to navigate which feels good when running. I prefer the Coros app to garmin, all the info on one page, very clear. Accuracy seems to be spot on. Best sub £200 w

atch on the market.

Super montre de sport ! Très bon rapport qualité/prix, énormément de données et grande personnalisation. Me permet de me challenger et me connaitre mieux lors de mes sorties running, cani-cross et randonnée tout en recevant mes messages téléphoniques sans devoir sortir mon tél

éphone de ma pochette. Seul bémol : paramétrages assez long et fastidieux.
