Engraved On The Movement G C T. Included is the Rare Brass U. Army Aircraft watch case with glass intact as pictured!!!! WWII 4992B Pocket Watch History. During World War II, Hamilton produced a variety of time pieces to support the war effort. 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. Here’s a couple of advertisements from WWII-era Life Magazines that featured the 4992B. You’ll often see 4992B’s in a case or a box that was intended to isolate it and protect it from shocks or accidental damage. If you look closely at the dial, you’ll see that it’s a 24 hour dial so it takes a full day for the hour hand to make a full rotation. 12:00 noon on a 24 hour dial looks like 6:00 on a 12-hour dial. The minute hand still makes it around the dial in one hour, so the ratio of the minute hand to the hour hand is modified using a different minute wheel and hour wheel ratio.

This is serial number C7019. It has a Gold center wheel. This is a seldom seen U. Army marked Hamilton 992 B. These are usually only found in the Hamilton serial numbers under C10000. After that they are marked U. The watch has been running for over a month and keeps good time. The Plates are clean and I don’t see any scratches or screwdriver marks. The original Hamilton dial #024 is a Single Sunk enamel Montgomery. I looked it over with a loupe and did find a small hairline at the 1 minute marker on the edge. The case is the correct Keystone Base Metal Military model. The serial numbers on the center ring and back cover don’t match. Very few of these Military watches have matching case numbers because of the way they were cleaned in groups and no thought was given to matching up the case serial numbers in the Military. I don’t end auctions early. I don’t part out watches for higher profits and discourage this practice. The item “U. S. Army Marked 992 B Hamilton Running, Good Dial & Military Case No Reserve” is in sale since Sunday, April 03, 2016. This item is in the category “Jewelry & Watches\Watches\Pocket Watches\Antique”.
