How to Perform a HARD RESET on Your Samsung Galaxy Watch 4 – If You Can't Access Your Watch
The easiest way to reset your Samsung Galaxy Watch is to use the physical buttons on the device. The process is nearly identical for all watches, whether you have a Galaxy Watch 4 or newer with Wear OS, or an older model with Tizen OS.
Start by turning off the watch. To do this, press and hold the Power/Home button and the Back button at the same time until Rebooting appears on the screen.
Press the Home button quickly until the Select Restart Mode menu appears.
