I recently purchased a 21 Jewel Getty Sangamo (S/N 1844653) movement without the double roller markings on it. The dial is in rough shape. Most of the ones that I see online have double roller markings. Is this an uncommon variant?

It was listed as a parts movement. I paid $67 for it. I received it, cased it, and wound it.

Nothing happened which wasn't a surprise because it was, after all, sold to me as a parts movement.

I figured that I would have it serviced at some point in the future so I left it on my desk. It started running without any prompting from me two days ago for not apparent reason and keeping decent (not great) time. I'll get a it COA'd in the near future and find a better case for it.

I guess it was happy to be home.

Paul, you have a rare watch indeed. The below example passed through my collection a few years back and is (as with yours) a prime example of the design excellence that helped propel the "flavor" of Illinois innovation throughout the rest of theirs (and Hamilton's) years of watch making. The "Double Roller" marking was not an issue with this piece. Yours is more than worth restoring though as fewer than 2,000 were made.

2000 21j Getty Sangamos total? Or 2000 without the Double Roller marking?

Eric,

I show 2,440 total production of the 21 Ruby Jewel 6 position Sangamo model 5 with no mention of Double Roller.

And 11,295 total production for the Double Roller.

Thanks, Paul. I was pretty sure my example was fairly common.
