Review on Polar Vantage M Smart Watch, Black by Kiril Andreev ᠌

Not suitable for pool swimming. Functionality at the level of a swimming bracelet. I don't know how he behaves in other sports. I guess which is better. Different pros: The heart rate sensor in the pool from the wrist works great. No complaints. The accelerometer correctly counts crawl circles. Cons: The vibration signal in the pool is not audible. The number of strokes per swim pool is not displayed.
