It's the three step. Commador, Broker, Director. I think we decided the Commador has engraved vertical bezel. The difference btwn Director and Broker slip my mind....but this thread has some useful discussion on this proposed difference.
When I do a watch database search for this period Director, I see no engraving, and an date range beginning 1946 through 1948. Nothing with the dial of subject watch.
Doing the same watch database search for this period Broker, date range is 1944 through 1948. There is at least one listed as Rose with subject dial. I gave that Rose w/ subject dial two ticks as Broker.
I betcha subject watch is either Broker or Director....but I'm leaning towards Broker w/ this dial. William (Scott) gives some crystal specs in the first page of comments in the currently-listed Broker, suggesting the Director is slightly different than Commador/Broker.
