Polar - Vantage V3

meh... I was part of an Adidas study that paid me whoop for 1 and half year. I just recently renewed as I am definitely more athletic than before. In particular the increase in sleep quantity and quality was a big factor and I could not have achieved the same level of insight with my Polar vantage v3

Because I use polar since a lot of time and like it. It will be complète my vantage v3. The loop to wear when I want to wear a mécanical watch or when I sleep

So I already use polar ecosystem since over ten years. I already have polar v3 and other polar product. I was waiting for a product I can wear with mechanical watch.

Even the Vantage V3 with ECG won't detect aFib 🤷‍♂️

Coros is from US. Heart rate wrist measurement works really bad. I would suggest Polar Vantage 3 if the budget allows.

I agree with others, for distances under 5km, a dedicated sports watch watch isn't very advantageous over a more general smart watch like an apple or samsung watch. Either one of these will track sleep, recovery, heart rate, etc at a good enough level for anyone who isn't a professional or elite amateur. They also have good secondary market value, so if you do want to switch to a proper sports watch, you can sell the smart watch to recoup some of the cost. Remember, the devices only really do data logging and some basic calculation for fatigue, sleep, etc. They don't automatically make you a better runner. (Although having a fancy watch on your wrist certainly motivates you). If you are dead set on a sports watch, they are all great options. Pick which one looks best. And tip: you can always buy different straps. The same watch can look drastically different for the office, gym, weddings, clubbing, etc if you own a rotation of 3-4 straps. I personally have a steel band, black and tan leather and a silicone strap for my polar vantage v3.
