It happens that the watch is showing incorrect time. The difference was from few minutes to one and half hour. It happend 2-3 times when the Time Source was Auto. Thought it was the problem with phone communication and changed Time Source to Manual mode. It was OK for 2-3 weeks and today in Manual mode of Time Source it happend again - the difference was about 1 hour 20 minutes, luckily I noticed the difference at one.
Does anyone had such an issue? The watch is uselles with this problem, I can not trust the time I get!
I used to have Forerunner 610, Vivoctive and Vivoctive HR and NEVER had this issue with these units. I also haven't seen similar problem on the forum.
I think it needs repair/replacement.
