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.
This looks like there is a date code of X (1933) is the center of this photo by the 1 o'clock position near the screw.

I see. Thanks. Its tough to pick them up through all of the little scratches sometimes. They never seem to be as deep as the other markings.
I looked and didn't find a match yet either. Will keep looking but Unknown for now.
This is one of those models that keeps taunting us to find it's name. I know I've seen it before, but for the life of me cannot find anything on it.
I'm glad it isn't just me. There are a lot of ads there and I have been known to miss things in there. I haven't spent as much time with the part ads. Sometimes the quality of the scans isn't as good. But I'm looking through them today.
Neat watch, I'm also at unknown.
Funily enough I have a close up of the very area where that date mark is. I wonder if I spotted it when I took the pictures and forgot about it.
Anyway, this 6AB movement is marked as "1934-1935" in the movement range section. Should that be changed to "1933-1935"?

You may need to take the movement out of its cover in order to see the movement dats code properly.

Would suggest we update this one to Constance by this ad.
