935, FW 6.1 (saw no value in 7.6, especially with the need to re-install everything).
Stock watchface with hands.
Not sure when it appeared (previously used it actively for workouts, now since it is cold outside (10-15 C below zero) I use old 920 not to kill battery) - so I use it mostly as a day-to-day and pool watch - since January.
I discover watch showing incorrect time recently - being late first 2-3 mins (was surprized), then around 7-15 mins (!) and today discovered it late by 7 minutes.
Last GPS activity (and I think GPS time sync) was on Sunday
Monday - morning pool activity (no GPS) and evening stretch (connectIQ app)
Evening - alarm, Morning alarm.
I think (not sure) in the morning time was ok (I have alarm on my watch first and in 5 mins - alarm on my mobile I think (not sure again) the sequence was "normal" (first watch alarm then phone alarm - which means watch could not be 7 mins late).
Then I put the watch off hand and left it for a while.
Then discovered it is 7 (seven!) minutes late.
Anyone had similar issue? Any solution?
