Well, I have this 1917 (some sources say 1918) pocket watch that was converted to a wrist watch for use in the trenches during WW 1. Note how the 12 position is in the correct place if you were hanging on to a ladder and about to 'go over the top'.
Anyway, I need to replace the crystal and the face and give it a good internal cleaning but I cannot even figure how to remove the crystal. On my other Elgin pocket watches from earlier than this I can just screw them off. This seems to be on there differently. Any tips on how to remove it?
The watch has seen 'regular' service. Once in 1945 and again in 1994. I guess the fifty year time span between trips to the service area might have been a tad overdue, so I wanted to clean it up before another 20 years has gone by.
Is there a good source book on the repair of these timepieces?
If it helps this is a grade 431, 6/0 size 7 jewels.
It will not start ticking on its' own, but if I place it face down and nudge the wheel with a pencil lead it will run. Sometimes fast and sometimes slower. The change in speed is so abrupt you can see it taking place. It will only run in the face down position.
Any comments would be more than welcome.
