This week - the old Speedmaster gets the elevator photo! Managed to snap it off just before the women from the fashion house downstairs got on too.
Mido Multifort bumper automatic, I am guessing late 1940s or early 1950s. Bought at an estate sale, complete with warranty and original box with outer shell. I watched a guy pick it up, ogle it, and put it back down. As soon as I could do discretely, I gathered it and an adjacent GP with wind indicator up. Paid (very little), and departed. Don't wear it often. Too small for my big wrist.
