Hello, thanks for the details !

The most tricky part: find the right spare part. I can’t find a replacement battery that could fit the original dimensions with reasonnable capacity.

Do you have any lead?

In case if anyone is still looking for the spare part I have just replaced my M400 battery with this one: https://www.aliexpress.com/item/10050045...
Replacement instructions were detailed enough to get my watch to work again.

Once the battery is changed, the M400 does not work. Do you have to press any combination of keys?
