Hello Gordon,
sorry for the late reply, I only got the reply notification for fanoush and forgot about it later.For my watch:
- no showering with the watch
- the one contact which always has a voltage applied is corroded quite a bit, but this should not translate to inside the watch over time, hm?
- battery also seems not inflated
When I find it again (not sure where I put it, and its not where I'd expect it to be ;) ), I will try if a complete drain has helped, but I have little hope right now...
- no showering with the watch
Does squeezing in the top right make it come back to life? That's usually the sign it's a hardware issue.
In the very first KickStarter batch there appeared to be an SMD soldering issue in some watches and it seemed the chip itself lifted slightly off the PCB, which is why we replaced those ones. But since then the rate of failures has been very low.
The aerial is part of the case, and the connection to it is made with a gold-plated contact from the PCB to the case. If your watch was getting wet inside (do you shower with it?) the aerial contact could get corroded over time and then lose contact?
If that's the case, repeated squeezing might make the contact move slightly, wear off the oxide and it might start working semi-permanently again.
The other possibility is the battery expands slightly and pushes the PCB away, breaking the contact, but I haven't yet seen any watch with any sign of that happening.
