I don't know what got into me but I had a vintage LED watch craze phase a few weeks ago. A Wittnauer LED watch with 1 pusher at 1 o'clock and a recessed button at 7 o'clock. The back doesn't look like a screw-back. I can't find any of those flat areas to stick a flat blade under to pry it open. It seems stuck. Any ideas on getting it open before I have to go to the watchmaker.
