Bulova 1947 Princeton

I'm thinking early (first half) 1947 based on the case serial number.

May or may not be correct, but having a notional number in mind may help us deterime first or second half of the year, thus Princeton Vs His Excellency.

Christmas 1946 saw this watch advertised as the Princeton and as part of the "Excellency Group", which in 1947 became the "His Excellency" and "Her Excellency' line of watches. When that cut over was is anyones guess, but there may be a hint in the adverts during 1947.

Bulova Princeton for me, but could easily be pushed off the fence to the HE side if others have a nicer theory or evidence.

Here is a list of watches from 1946-48 with a 21 jewelled movement and a round case serial number starting with a '7'
