Unsure of an ID for this one. The case has the same shape as a Spencer but the dial seems wrong. Case is deep yellow gold color. I have a couple of rose gold watches and this color seems off from those, but still different than normal yellow gold(may just be wear and aging). Exploding style dial with black numbers. Serial number begins with a 1 and the 8AE movement has an asterisk so I believe it is a 1941 watch. As always, thanks for any information!

Not necessarily, I have seen plenty of factory dials with a notch present.

This old Omega watch thread debunks a notch indicating a redial theory.

1941 'SPENCER' would be My ID for the subject watch.
May or may not be a redial, but I don't think its makes a difference.
I would also ID as a 1941 Bulova Spencer.

as a point of interest, this late 1940's early '50s Bulova dial also shows a notch at the 6 o'clock position.
Refinished?
I highly doubt it.
