Ahh the penny just dropped, sort of.
In 1946 it appears that Bulova grouped a number of their top line 21 Jeweled watches as the all new 'Excellency Group'. Then in 1947 Bulova release a number these 21 jeweled watches as 'His Excellency' or 'Her Excellency' followed by 2 letters in indicate the model variant.
The 1946 mens watches that looked to have formed the 'Excellency Group' are:
- Tudedo
- Princeston
- Ambassador
- Statesman
- Treasurer
- Director
- Craftsman
Some of these (not all) looked to have been rebadged as 'His Excellecy' models in 1947.
Bulova seemed to really pushing the 21 jewel line during 1946/47 as the top of the line watches.
So it'll come down to the line with Geoff's watch at the top of this post. if it was infact sold in 1946 then its more likely to be a Director, but if it was sold in 1947 then its a His Excellency, model ??
I notice that Geoff has indicated that the movement is stamped 47.
