Overall Length: 31.5mm Case Length: 23mm Width: 20mm Inside Lugs: 16mm Movement Date Code: L1 (1951) Solid 14KYG I checked the ads from 1948-1954 and did not see a model that matched. The glass crystal appears to be original as it is faceted to match the case in both directions. ***UPDATE*** 02-23-2012 - Found RMS 122-72C Bulova "Patriot" crystal info on page 33 of the Rocket #9 crystal catalog. Didn't have the Rocket but did have the G-S equivalent CMX 320-37 and it is a perfect fit.
I found a crystal marked "Patriot" that is a perfect fit and is perfectly faceted to match the case shape. I searched the ad's for "Patriot" (some reason Patriot is listed twice) and came up empty. I also searched Watches for patriot and there is only 1 modern one from 1991 listed. I'm confident enough to change the model to Patriot based on the crystal info alone until such time as evidence arises to contradict. Thoughts?
