Illinois Getty Sangamo and Bunn Special marked case

I don't think most watch companies started doing factory marked cases until the early 20's so if I purchased a Getty Sangamo from the 1910-1913 time frame it more than likely was not factory cased. From what I can find the serial number for the case would place it some time in the mid 20's. case sn 70xxxxx.

You are correct. Plain Sangamo's were never offered in a factory marked case. Only later when the "specials" came along.

I put most of mine in nice Dueber 10K Pyramid Bow cases, one of my favorites for Sangamo Specials, and the earlier Sangamos look real nice in a crisp french bow case of some kind

Correct me if I'm wrong, Terry, but I think that only model 10 23J Sangamo Specials came in those marked cases. I believe the 19J and the 21J did not come in marked cases, and of course none of the early Sangamos did.

I never was a big fan of that SS marked hinged front and screw back model.

I don't think it is altered this is a factory marked case but a "Bunn Special" marked case which I think would still be a standard 16s and not the 17s that the later Sangamo cases were.

The watch arrived today and was better than what I expected. The case is marked, Bunn Special upper part of the inside case back, lower portion is marked 10K Wadsworth quality with the serial number 7069484.

The movement is sporting a Montgomery dial with diamond hour markers sn 2452013, It is now in a Deuber French bow 20yr case that has a nice design on the back. Dial, movement are all excellent to near mint and the hands are good but not excellent.
