In fact, all of Hamilton's production was dedicated to defense purposes. However, they did still produce some wrist watches using excess movements produced in the 1920's. One of the war-related watches was a pocket watch with a central sweep second hand. The movement was based on the 21 jewel, 16 size 992B movement. However, an extra jewel was added to support the second hand pinion, so the movement got 22 jewels and was called the 4992B.
The 4992B is known as a "Navigator's Watch" as it was used by aviators to aid in navigation by the US Navy during the war.
