This is my Elgin 12s grade 345 17 jewels from 1922. It resides in a Philadelphia Watch Case Co. 'Victory' case. The watch is running, but clearly needs service. I have decided to make this the subject of my first attempt of watchmaking... I got it for a very affordable price, and total grade 345 production run was 730900 pcs, so it will not be a total disaster if I screw it up... I will be prepared with the minimum of proper tools and reference guidebooks though. This is hopefully not the last chance to show it here, but who knows. Unless someone thinks this model is not the best candidate for an amateur to start with?
