I have a Huawei Watch W1 Active and the screws are smaller than the T3 Torx ones. Is the hardware of the Huawei Watches W1 different depending on the model? I’m trying to use a T3 Torx Wiha Precision ESD 278 and it is bigger than the watch holes.

I bought a kit on ebay and followed these instructions. They were clear and SUPER helpful. THANK YOU!!! I’m so grateful I’m able to extend the life of my watch for a fraction of the cost of a new one especially since this model is discontinued.

Ensure to place these screws separately from the Torx screws, as they can easily be mixed up.

Screws are very short so expect them to unscrew quickly. Also if the battery is old and has been swelling, the motherboard will pop up, be sure to expect that so you don't lose any screws.
