Used to be fascinated by 'em, not so much anymore. That South Bend had a broken mainspring, I asked Grandad if I could try and fix it... I was 11~12. He said "sure" certainly figgerin' I'd NO chance. Asked my dad to borrow his small screwdriver set and went off to the bench to learn about it. I reattached that mainspring to the post it had snapped from with solder and re-assembled it. It worked!
...and I ain't been right since... :smirk:
My "dress" watch is an Omega Seamaster, forty years old. Everyday timepieces are a Swiss Army phenolic black bezel, nylon/leather band, black face and another one with a metal band and white face. A few Sieko and a Waltham in a drawer someplace.
