A lot of watch for your buck!

I've had this watch for around a week now and used it nearly every day. Bought it based on other reviews saying that for a mid-range watch you get a lot of features for the price, compared to other brand watches. I definitely agree with that! I bought it for running, but it has a lot of other tracking features that I wasn't aware of e.g. skiing - so I will use it in the alps next week. From first impressions the polar app is presented nicely visually, and easy enough to manipulate the date - you just need to do some reading up before hand.

mooi, goed en betrouwbaar sporthorloge

Heel tevreden met dit horloge. Als je eenmaal door hebt hoe je de schermen aan je eigen voorkeuren kunt aanpassen (via website flow.polar.com account maken, op je naam klikken en bij sportprofielen je schermen instellen) dan heb je alles precies zoals je wilt en kun je er tijdens je training veel gemak van hebben.


  • Draagt licht
  • eigen schermen instellen


  • het is wel even zoeken hoe customizen werkt
