Cool watch and interesting mystery dial.

I wonder if you could take another pic of the entire movement? There is a discussion in a couple of other threads regarding what appears to be a chevron symbol on the 10BZ movements and I am curious as to whether or not yours has it. It could be out of the frame on your existing pic or underneath the rotor.

Wow !

commonly known as the 'MYSTERY DIAL' but did Bulova place the mystery dial into several different models?

The nicest I have seen to Date, mint.

Fantastic watch.  That thing is 52 years young!  I've seen Bulvoa mystery dials, but never seen this beauty.

So, according to the ad, it's a '23' with what we are calling a 'mystery dial' Now that I see it up close, it is even more interesting than I thought. I have seen other maker's versions with acrylic or plastic discs, carrying the 'hands'. This is a much cleaner, and longer lasting execution, I would think. The plastic discs would often warp with age. I think it is entirely plausible that Bulova put the mystery dial into various models.

Bulova used metal for the dials. I just had one refinished, thouh I'm not sure what metal was used, it is metal.
