I received this watch a few weeks back. I think it's a 1957 Surfmaster "D". It looks like it's never been opened and I've never attempted to open one of this configuration. I wanted to get a few photos of it on here before I possibly scratch it up. When I received it, it was completely wound down. Thought I had gotten extremely lucky, but after winding fully it didn't run. I'm thinking it was running when put away somewhere. I can't measure the crystal. My digital caliber decided to become demon possessed today and reads random measurements and won't zero. I took the battery out and dropped the cover and where it landed is still a mystery currently.

Elgin used a special glue substance to attach studs to the hairspring that would hold up to submersion in alcohol for 60 seconds. But this substance was not sold to watchmakers. The factory repair manual says that if the hairsping is accidentally exposed to alcohol for longer than 60 seconds and comes loose from the stud, shellac should be used to reattach the stud. Seems like this method should work with Bulovas also if you have a stud.
