Hi guys, old watch not used for about 2 years. I put a new battery in, went through the ac reset procedure but it still displays 'open' on the screen. The digital watch resets to 12 obviously, but not one button functions.
It is a protrek prt-50 and module 1376.
Somebody said it could be a spring that has fallen out that needs contact with the casing. I can provide a picture if that helps.
Going away to New Zealand on Sunday and really wanted it sorted by then...
Help muchly appreciated.
