Presented
is a very rare WW II Waltham chronometer watch which is mounted in a fine three tier Mahogany case all of which were
made to military specifications. Note the San Diego instrument maker’s label of the period in the picture above. It was recently rebuilt
by a certified master clock maker and has three new springs fitted. It keeps near exact time in concert with a quartz comparison
watch and runs continuously for over nine days.
 
The first mounted chronometer watch purchased
by the Naval Observatory was made by Waltham in 1907. The first was serial number 16,628,501. Over the period of
29 years, ending in 1936, Waltham made 16,000 of these clocks with the final serial number being 28,924,500. This one is serial
number 22,1XX,XXX which dates the clock to 1918. Waltham “Military Spec” clocks were prized for their accurate timekeeping
and the high quality of their cases.

 
MILITARY SPECIFICATIONS:Those
that were especially made for our military, Navy, Coast Guard, and Maritime Commission, had an eight day, 15 Jewel movement
and were housed in a three tiered, metal strapped, Mahogany box with gimbals. The silver etched 2 9/16 dial had black
Roman numerals. Navy specifications required that it have an 8 day count down indicator in lieu of a “spot” indicator. All these
are present in this example.
          15 Jewel, 8 Day chronometer movement. keeps perfect time.
The tub is brass with a screw on
bezel. It is wound by a large knurled knob on the top which also sets the time when pulled out.
The hands are gun metal blue spade hands. It is fitted to a top opening Mahogany case which measures 4 7/8″ x 4 7/8″ x 4
7/8″ 
 
Military chronometers
of the WW II Era made by all the approved manufactures were made to the exacting standards of the specifications
established jointly by the military and the U.S. Naval Observatory. Tests showed that there was no significant difference
in accuracy between 15 and 21 jewel clocks.

CONDITION:  This
example is in outstanding original condition with a dial and movement that shows only minor evidence of natural
aging. It was recently serviced by a certified master clock maker and has three new springs fitted. It keeps near exact time
in concert with a quartz comparison watch and runs continuously for over nine days. The wood case is also in outstanding
condition with only a thin scratch on the left side. It has a wood bung on the right rear and at the back. There are minor
marks of handling as
 are to be expected with a timepiece of this age and use at sea.
