Hamilton Military Pocket Chronograph Watch Repair

Repair Service of a 1942 16S 19 Jewel Hamilton Pocket Watch from World War II

These Hamilton Model 23 Pocket Watches filled an important role in World War II as a Navigator’s Watch. The chronograph function allowed navigators to check ground speed in flight so they could determine the correct speed for bomb drops, paratrooper drops, and fuel consumption. They were issued in conjunction with the Mark III Model 5 Octant Navigator. This device was handy when flying over water and when landmarks were not available. The device used an artificial horizon, like a carpenter’s level. A bubble the navigator would look through and use to align horizontally and measure altitude from a celestial body.
