Serial #18237826. 15 jewels. Made in 1912. I *think* it has a gold mainwheel.
Nabbed it off eBay for $17, and the description said it was broken.
In truth, it seems to have fallen victim to having its case scrapped for gold value, and the roller had simply jumped the pallet fork (a 5 minute fix).
It was in perfect shape otherwise. I mean besides a smidge of corrosion on one of the jewel settings, it’s almost brand new. Not bad for a 101 year old watch. 🙂
(I need to get some better pictures to really show it off.)
