Unfortunately, I cannot get the back off to check the movement caliber. I have tried in the past and again today to no avail. It hasn't been in for a service yet, so.......... eventually. There are three pin heads (should be four...one is missing), that look like screw heads without the slot, one seated directly next to each lug. I cannot budge them! I imagine the missing one flew across the past owners room and was never seen again. : ) They are somewhat visible between the case and watch strap.
Agree 1957 Bulova 23 "U" it is
1957 23 U it is. Good ad matches.
I agree, Bulova 23 'U'.
Not sure how the case disassembles; almost looks like a press case where the crystal and caseback separate out together from the rear.
Crystal is glued to the bezel.
I can't remember seeing this model before. It's great to see these new additions. Thanks timeless!
