A classic U.S. Navy WW II ships boxed chronometer which keeps
excellent time, and is in fine condition all around!
Presented is a WW II Longines chronometer mounted in a single
tier Mahogany case. We believe this to be a Longines No. 21.29 Calibre since the movement runs for 36 hours. However,
the movement is supposed to be 6,411,644, Ca 1941 and should contain 17 jewels and adjusted to three positions,
but this one is clearly marked:
Longines Watch Co. Swiss
Twenty One 21 Jewels
Adjusted to Temperature
And five 5 positions
The face on this clock is also unusual because the outer ring is minutes and the
inner ring is calibrated in 24 hour time. That is rare since most of these military chronometer clocks had standard 12 hour
dials. The up down indicator has 6, six hour segments for a total of 36 hours.
The case is brass with a screw on bezel. It is wound
by a knurled knob on the right side 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 6″ x 6″ x 4 1/4″
Maritime and 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.

As a matter of note, Marvin
E. Whitney in his book Military Time Pieces worked in the test room of the Naval Observatory when tests were done on these
watches and on page 296 & 297 of his book Military Timepieces he discusses and has pictures of both the 17 Jewel 36 hour
movement, and the 50 hour, 21 jewel movement. But he makes no mention of a 36 hour 21 jewel movement as in this example. He
says that as far as the Naval Observatory was concerned, rate-wise the accuracy of Longines was comparable to that of fine
