After 2.5+ that I have drunk the blood, I can say it is unbelievable. Generally, in many cases, I don't know anything that didn't turn out well.
Accuracy in its measurements..in all its measurements, even in sleep and even in points without signal.
Readable screen that allows you to continue training undisturbed..infinite conveniences such as automatic backlight, and easily removable strap. Screen resistant to hardships. One negative aspect is the touch screen which I do not love when it comes into contact with water.
Although what I have endured is not even 1400 1.5-hour workouts or 14000 km without ever leaving my hand, I will repair it otherwise I will get the same.

Once again, Polar is making the best sport watch on the market.
Far from expensive trends (like Garmin) that everyone wears, but only a few use properly and whose measurements and ecosystem are of questionable quality, the Vantage V2 measures everything with absolute accuracy, synchronizes seamlessly and quickly with your phone, has a battery life (in my case, with 4 workouts per week) of one and a half weeks, and powers the - by far the best of all - Polar software with everything!
It's not a beautiful watch that you should wear on your walk (not that it's forbidden) like Garmin and I can't evaluate its smart functions because I don't use them!
The fourth Polar watch I've purchased and for the fourth time I am very satisfied with everything!

I have had the watch for about 6 months, I would say that it is a very good watch with great accuracy in its measurements, and in collaboration with the Polar application, you can see a lot of things related to workouts, sleep, etc. I have bought several Polar products, but what saddens me and would be a reason not to buy another Polar product is the connectivity of the devices with mobile phones or other devices. They need to take this issue very seriously at Polar! I cannot justify spending 600 euros on a watch and struggling every day to synchronize devices with mobile phones, heart rate monitors, etc.
