This was my first win on the bay about 7-8 years ago. Never had the chance to take decent pics of it till last night. Yeah, I'm lazy! Here's some info I got from Longines a while back...
-Wrist watch in 0.925 silver, rectangular shape
-Movement calibre L 9.47
-It was invoiced to Messrs LONGINES WITTNAUER Watch Co. in NEW YORK who were for many years our agents for the USA on 26th January 1924.
Thanks for looking!
