You need to unscrew the other end of the latch with a small Phillips screwdriver, then it will flip up.if you are careful and have the new battery ready, you can slip it in place without letting he screw fall out of the hole in the latch. Sent from my iPad using Tapatalk Pro
Picked up the Swiss case from eBay, brand new but from the sixties I believe. Unfortunately can’t source a 10 1/2 mechanical movement so fitted a Swiss Ronda quartz movement. The dial is a genuine 1963 uncirculated half penny which I machined down to .5 mm and then silvered.
I made it for my wife's birthday who was born in 1963. She absolutely loves it
Just normal dial silvering compound
