Restoration of a World War II era Waltham 1942 A-11 military spec wrist watch. These watches were produced in the 40s for pilots and navigators in the US Army Air Force USAAF (as well as the Navy and Marine Corps) and the A-11 is one of the most iconic World War II military issue watches every produced. Many were manufactured during the war for allied soldiers and features a black dial with white indices, a sweep seconds hand (which was relatively new for military watches) and outer minute track.
This particular A-11 was made by the Waltham Watch Company in Massachusetts in 1943, according to factory records. Waltham was not the only company to produce watches to the A-11 specification. Other manufacturers such as Elgin, Hamilton and Bulova were all contracted by the US government to produce these timepieces.
The watch contains a feature known as the "hack", or balance braking. Hacking was a common way to synchronize time prior to the advent of GPS. This is achieved by mechanically stopping the balance wheel from swinging so time can be set without time progressing.
Restoration included full service of the movement, including replacement of the broken balance staff and static poising of the balance wheel. I also stripped and replated the case with nickel.
