1934 date is based upon the case serial number and the 6AB movement (1934-35). For the life of me I can't find a date code on the movement. Sometimes they are partially hidden under the edge of the sealed case but I can usually find at least a part of one.
The case is marked "Bulova" but its on the top edge and hard to see. I've supplied a picture.
It has an expansion band that might be original.
The watch runs like a top.
This one could be a challenge. I've been through the ads a number of times and I've found a couple models that are close but I can't find one that quite fits it. I'll be interested to see what you guys come up with.
