CHELSEA WW II U.S. NAVY MARK I DECK CLOCK COMPLETE EXAMPLE 3 PIECES Naval Observatory Cartouche 1941 Presentation Quality STAND INCLUDED A $75.00 VALUE The WW II Chelsea MK I Deck Clock's case was made differently than the ubiquitous nickel plated Seth Thomas version. It is more refined and far better looking in polished brass. DIMENSIONS: 5 1/2" Diameter of face 3 1/4" Deep 8" Full Diameter Weight 10 lbs 6 oz Presented is another outstanding example of a Chelsea, back winding, Navy MK I Deck Clock with a hinged front that is complete with both backing plates making up 3 pieces. Originally, one plate acted as a water tight cover and shock absorber and the other mounts it to a bulkead or wall. It is unusual to get this clock with its back cover plate and more so with the original mounting plate making this an even rarer exception. The Chelsea version of what was supposed to be a standardized mil-spec design is more refined and has a different hinge arrangement than the thousands of nickel plated clocks that were made by Seth Thomas. This clock is in polished brass with a lacquer coating to preserve its luster. The movement, serial number 286932 dates from 194. It is keeping good time compared to a quartz comparison watch. 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 are unique. The front section holds the movement and has an integral stud on the backing plate that acts as the hinge. This compares to the more common Seth Thomas version which uses a removable pin, and has a chrome plated case. In both designs, the back of the front section has all the controls on the rear. Chelsea clock has an integral stud on the mounting plate as a hinge plus shock damper. 3 pieces total Typical Seth Thomas MK I casting uses a separate pin as a hinge Both Andrew Demeter in his definitive book, "Chelsea Clock Company, the first 100 years" and Marvin Whitney in his encyclopedic work, "MILITARY TIMEPIECES" say that these clocks were chromium plated up to 1941 when cases were switched to Bakelite, a phenolic.
