Change language and orientation
Change language or region format. Open the Apple Watch app on iPhone, tap My Watch, then go to General > Language & Region.
Switch wrists or Digital Crown orientation. If you want to move Apple Watch to your other wrist or prefer the Digital Crown on the other side, adjust your orientation settings so that raising your wrist wakes Apple Watch, and turning the Digital Crown moves things in the direction you expect. Open the Settings app , then go to General > Orientation. To make the change using the Apple Watch app on iPhone, tap My Watch, then go to General > Watch Orientation.
