From 1942 to 1946, Hamiltons production was dedicated to the war effort.

Watches and time keeping devices of all sorts were produced for the US Government and our allies.

I posted earlier this month an example of a Model 22 Marine Chronometer.

Hamilton also made bomb timers that used the 140 980 movement in a special case with a hack function.

Some collectors have converted these cases to accommodate a strap although theyre technically not wrist watches.

Military personnel also were issued time pieces when they went into harms way.

Initially cases were made by three manufacturers - Wadsworth, Star and Keystone.

Some cases had screw on backs and some had a pop-on back (called a tea cup case).

Early cases were chrome plated and were prone to extensive wear.

They were eventually replaced by a parkerized case with thicker lugs.

These cases were used during the Korean war too - but with the 80 size 747 movement.

Parkerization is a special coating often used in guns as an alternative to bluing.

Early cases were engraved on the back with Ord Dept USA and a serial number starting with OD - representing a non-waterproof case with 15-17 jewels.

A letter was stamped between the lugs representing the case maker.

H, W, or S. H and W are Wadsworth cases and S was for Star Watch Case company.

As far as I know, Navy watches used Wadsworth cases, while the other services used both manufactures.

I dont have a complete collection though, so this isnt an exhaustive list.

Generally speaking, black dialed wrist watches were used by the Navy.

The dial will also have Hamilton embossed in black on the dial - albeit hard to see.

A watch like this one with the sub second hand at 6 will feature a 17 jewel 987A movement.
