After a Factory reset, I followed the entire protocol for optimal GPS signal acquisition, just like I always do.
There was absolutely no improvement — the same drift and many signal reflections over a distance that is exactly 500 meters in a straight line, marked with buoys.
I was pressing lap time as a reference to record the distance, and the discrepancies were 200 to 300 meters every time I completed this route.
Weather conditions were perfect — clear skies, and my hand stayed out of the water for 30 seconds of rest before starting the next set.
-Hard reset didn’t help-
I’m starting to believe this is a serious firmware issue and unfortunately can only be fixed with a new update.
Otherwise, the watch has a severe limitation in this specific function, which is unfortunately very important for my training.
Also I’ve achieved again 591km/h I think it’s a very solid performance for my swim freestyle technique
However, the watch continues to function perfectly in all other activities, with highly accurate GPS and absolutely no issues.
