One of many names can be said for this cat, but with the engraving I think we nail it down to the Galahad. New crystal on this one.
See the discussion of this case style here:
Not the Emperor.
This watch is exactly the same case as an Attorney, but engraved and in yellow gold. Look at the triple-stepped side on this Attorney in the DB, and it matches the subject sides and stepped lugs. The Emperor lacks the three steps, having only two.
This 1943 ad has the Brewster, Attorney and the 21 jewel Jefferson, all have their differences from the subject, which I think is a totally new and Unknown model. Also the engraving would give it a different name, as we have the Banker and Chief in the ad with identical layouts, apart from the engraving.
