Polar Street X or Vantage M3
I just ordered the Street X over the Vantage M3 yesterday. While the Vantage M3 is on sale now, it still cost SGD 150 (about 100 euro) more than the Street X. Having said that, I guess it depend on your use cases. For me I don't run a lot (but trying to do more this year), but do mainly strength tra

Vantage M3/Grit X2 questions
I have my Vantage M3 since May this year. It looks a bit beaten up already, mostly from hitting the watch on doorhandles. While this watch is thinner than my previous watch, it sits higher on my wrist due to the way the lugs attach to the strap. There's a very fine crack in the screen, as in thin as

V3 firmware update
The best part is that Polar has had the software for the Vantage M3 for several months now, but for some reason is artificially prolonging the release of the update.

Can't update my Vantage M3 to firmware version 5.0.12
I have the same issue with a Vantage M3 bought directly from the Polar onlineshop in November 2025. I tried with polar flow on Android and with FlowSync on Windows. I dont get an update notification in either of these apps. Hope this will resolve soon!

Watch restarts after doing manual setup and app sync not completing
I am having this same issues with my Polar Vantage M3 that is only about 4 months old. I can no longer do the computer sync and the watch gets stuck in a loop where it just wants me to manually reset over and over on the phone and shuts down and reboot before completion. I entered a second support t

Considering M3
thanks for the answer, the only thing i don't like about polar is that it doesn't have resting heart rate. I can't decide between coros pace pro, polar vantage m3 or fenix 7s pro sapphire. I don't like garmin's app, but of the three watches fenix is the most beautiful and offers more metrics that i'

Altitude gain vs. altitude profile completely different
Je constate un comportement similaire sur ma montre Polar Vantage M3 depuis la mise à jour du firmware v 4.1.1. au mois de juin. Les données de dénivelé des sorties VTT sont fausses. Sur un parcours que je fais habituellement avec 500 m de de dénivelé, le résumé de l'activité n'indique que 120 m de
