Hi,
First to mention that I have Iphone 6 so no app on phone is available for me, so I use Garmin Connect from Windows 10.
First I had issue after time saving hour change and then suddenly after connecting to 5 different PCs it synced the clock.
Currently new issue, my clock is going 9 minutes slower then actual time. I'm trying to sync it again on few windows devices by connecting the watch via usb cable, but nothing happens...
