The Samsung Galaxy Watch3 earns a 7 out of 10 on our repairability scale (10 is the easiest to repair):

The opening procedure is straightforward and glueless.

No overlapping design of cables, no fragile ZIF connectors.

The battery and display are easily accessible with some disassembly.

An uncommon tri-point driver is needed for the back cover—regular Phillips on the inside.

Most components are modular and can be replaced separately—except for the rear sensor array which is fixed to the back cover.

The glass digitizer and screen are fused together—meaning glass-only repairs will be impractical.
