A Mark I Deck clock made by Chelsea is a rare find, as is a clock of this age and service
at sea to be found in this fine condition. It is perfect for a collector of military pieces or as an important gift.
DIMENSIONS: 5 1/2" Diameter of face 3
1/4" Deep 8" Full Diameter Weight 10 lbs 6 oz
is a finely Chelsea made, back winding, Navy boat clock with a hinged bezel that is sightly different and more refined than
the numerous examples housed in nickel cases that were made by Seth Thomas. This clock's case is bronze which has the appearance
of being plated in Gold! A wood backing plate has been added to allow wall hanging. The clock is keeping exceptionally good
time compared to a quartz time piece.
Navy MK I DECK clocks
of WW II were manufactured in accordance with military specifications 18C-11 and 18C -13. This Chelsea example has modifications
which we haven't seen before. It's housed in a bronze case of Gold appearance, and with an integral hinge stud on the backing
plate that acts as the hinge. This compares to the more comon version which uses a removable pin, and has a chrome plated
case. The back of the front section has all the controls on the rear and couples to the backing plate by a fixed stud.

Andrew Demeter in his
definitive book, "Chelsea Clock Company, the first 100 years" writes on page 210 that Chelsea
MK I Deck and Boat clocks were chromium plated up to 1941 when cases were switched to Bakelite, a phenolic.
Chelsea case and backing plate pictured on page 208 in Marvin Whitney's encyclopedic work, "MILITARY
TIMEPIECES" is as the same as as shown here, but he also says it should be chromium plated. We wonder if this clock wasn't Gold plated for "Presentation" for which it is eliminately suitable.
