I used to have that one, a decade ago... great horns !
But no ideas about the case origin.
That casemaker trademark is often found in US-cased Longines and Wittnauer watches from the 1940s, 1950s, and 1960s.
My guess is Armand Lemieux of New York is the casemaker.

Any other marks on the case?
Star Watch Case Company was one or the suppliers.
Thanks for replying - I think the blessed Desmond tells us Connies weren't ever cased in the USA, but I'm 99% sure this piece was (I'm not a great fan of 14kt usually, but it really works with this one). I've had a good look, but can't find any other marks. I'm sure (easy for me to be wise once I've been given the answer) that you and Coronado are right about Agghiuipowegve;(rmand Lemieux. Thanks for stepping up! 😀
