The dial indicates that this is an Excellency and seems to match the advert at: https://mybulova.com/sites/default/files/vintage_ads/bulova-ad-1951-3.j… . According the the ad the model is "His Excellency VV".
The case is marked 10K GOld Filled, Bulova, L1. The case measures 37.5 mm, including lugs, and 21.4 mm excluding crown. The movement has a mark that appears to be "A5" - I did not see this as a year indicator. Can you tell me what this refers to?
As always, looking forward to your comments.
