The OnePlus Watch earns a 5 out of 10 on our repairability scale (10 is the easiest to repair):

The opening procedure is straightforward and glueless.

Only two common screw types are used throughout the watch.

Some finicky metal brackets and a few overlapping cables complicate repairs.

The battery itself is easily accessible, but connects to the motherboard via the sensor flex assembly.

The sensor flex assembly is non-removable and fixed to the back cover.

The display is difficult to remove and requires heat and special prying tools.
