The watch is not working. It has a very rare and unusual dial. The screw down hacking crown is sheared off as shown. Sold as-is. Type A-11 Weems watch issued to Air Corps pilots and crewman. Unlike the later A-11 watches made for the AAF by Bulova and Elgin during WWII, the earliest A-11's were the Longines Weems Model watches, which were tested beginning in 1937 prior to the standardization of the A-11 in May, 1940. The Type A-11 white dialed Weems were produced by Longines-Wittnauer and LeCoultre under the earliest 27834 specification. The Weems watches had a movable numbered bezel to synchronize the time to the radio time signal or hack, rather than the later A-11's sweep second hand with a hacking feature, which stopped the second hand when the crown was pulled out. In the Weems A-11, the bezel is rotated in synchronization with the second hand until the time hack is heard, at which point the small screw stop is tightened down.
