I beilieve that this watch could be a Dewey as seen in the 1947 adverts' #25 has the discription and #26 has the picture. I am looking at #54 in the advert. Case 35.40mm lug to lug x 23.60mm not counting the crown. I had the dial redone as exact by International.

Cambridge case is actually different to the Dewey.
There is a kind of "crease" or "recess" top and bottom centre of the bezel, and can be seen in both Cambridge ads. The case is squarer than the Dewey model's too.
Here is the 47 Dewey ad, matches the subject.
DEWEY, 3 tix.
