The power button on a Garmin 305 is covered by a
thin rubber sheet that is part of the watch body.
The sheet covers a small plug that goes inside the
watch to contact a micro-switch. Over time the
rubber deteriorates until the rubber plug falls
out and the watch is exposed to rain, and the
on/off has to be activated by a toothpick.

I have tried putting my own plug in place and
covering it with a dollop of silicone, but that
only lasts a few weeks before it peels off.

I would appreciate any suggestions for how I might
hack some fix for the missing plug. Maybe a
suggestion for something better than silicone to
hold the plug in place (it has to be flexible enough
to allow the plug to move down to activate the
switch).

Thanks.

Assuming you can safely get inside, wire in a lead and then an external
arrangement to do the same
