Introduction
What you need
Step 1
Unfasten the screws
- Opening the Mi Watch will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your watch without replacing the seals.
- Before starting the disassembly, turn off your watch.
- Remove the four 3.2 mm-long T3 Torx screws on the back of the watch.
- A T3 screwdriver has a tight fit on these screws and might require a bit more downward pressure to unfasten the screws. A T2 fits as well but poses the risk to strip the screw heads.
