Hamilton 4992B G.C.T. Master Navigation Pocket Watch – U.S. Army Air Corps (1942) – Working Hack Feature

Offered a beautiful and fully original Hamilton Model 4992B 'Master Navigation' pocket watch from World War II. This extremely precise instrument was produced in 1942 under an official military contract for the pilots and navigators of the U.S. Army Air Corps (the then United States Air Force). The watch served at the time for vital astronavigation aboard Allied bombers and transport aircraft.
The back of the original 'Base Metal' case features the fully correct and sharp military engravings:

• AN 5740 (Military standard specification)
• MFR'S PART NO. 4992B (Model number)
• SERIAL NO. AC 42-3841 ('AC' stands for Air Corps, produced in 1942)
• CONTRACT NO. W535 ac-28072
• HAMILTON WATCH CO.

Features & Condition:

• Dial: Original, deep-black 24-hour dial with the three characteristic white hands. Very good, authentic condition.

• Movement: High-quality Hamilton 4992B caliber with 22 jewels, adjusted to 6 positions.

• Operation: The watch runs well. Crucial for collectors: The rare 'hacking' function (second stop when pulling the crown) still works perfectly and stops the seconds hand immediately for exact synchronization!

Movement: Fully original and factory-engraved with "4992B 22 Jewels" and "Adj. Temp. and 6 Positions". This master chronometer-quality movement is in a very clean and glossy condition.

A unique and functional piece of military aviation history, perfect for the serious WWII militaria and vintage watch collector.
