I use to pride myself with figuring most anything electrical or mechanical until now. The Daughter bought me this quite a few years ago and of course it takes a battery. Took it to a watch place last time and he took it to the back (seems the change of battery is top secret). He came back all done and $25.00. There are no divits to pry off, I have tried unscrewing (lefty loosey, righty tighty) with no luck. Anybody seen something like this or any ideas ?. I am really getting tired of scratching my head and arse trying to get this thing apart for a $2.00 battery.
