Vintage WWII U.S. Army M2 Message Clock

Presented is an original WWII U.S. Army M2 message center clock. The clock was made by the Chelsea Clock Company in Boston, Massachusetts. 

This M2 Message Clock model was first produced in 1943. It has a 12 jewel, 8 day Chelsea 12E movement with a 11 jewel detachable lever escapement, sweep second hand.  It is mounted in a dust proof and moisture proof black phenolic case with a 6" dial. It features a hour, minute, and second hand as well as another hand for a second time zone which is slaved to the hour hand. Fully wound, these clocks could tick for 8 days.

The US Army used these clocks from WWII to the Vietnam War. They were used in the field to mark the time when a message was received. Per the June 1944 issue of "Field Artillery Journal," there were to be three of these M2 message clocks in each infantry division. One clock was used in the message center, one in the forward command post, and one in the rear command post.


Good condition overall. Clock is presented without a case. Front glass is missing. The back of the clock is stamped "Chelsea Clock Company, Boston"  with the numbers "627286" written above. Dimensions: 6 1/2" H x 6 1/2" W x 2 1/2" D.
