This is a Bulova ladies watch in 10L RGP (White Gold Plate).
Inside case: 3763, 57
Outside case: Bulova M7, 10K RGP Bezel, Stainless Steel Back, 108476.
The Movement is 5 BA.....not in DB.
This one looks to be from the Concerto line. 1969 ad shows a variant, but I cannot make out the second letter, perhaps YT or YZ.
Concerto looks like a match. Too bad the ad quality isn't better. If I had to guess, i'd say it's "YT".
Until a better resolution ad surfaces, I'm good with 1967 Concerto - no variant.
1967 Bulova Concerto
Shown here as the Bulova Concerto 'BD'.
Advert dates to 1967.
Seeing different bands between the variants shown above, perhaps the band makes the variant. Current band does not look to match either ad, so I am good with Concerto, no variant.
In reply to Seeing different bands by Andersok
Agreed.
I like it, I'm going with Concerto as well
