New Fenix 5, updated to fw 11.0
I live in Paris, +2 GMT. The sunrise is shown as 6am in the standard watch face, it is in reallity 8am.
There's a bug in your watchface module.
Thanks.
I had the same problem with Enduro ver 25.1. The widget showed no daylight saving.
Go out to have a GPS signal. Go to Menu (long press) => System => Time => Time Sync
Wait until it syncs with GPS. Voila, your times are now adjusted.
