Chelsea Clock Company. 11E Deck and Engine room clock.

This marine clock has a spring wound movement that is designed to run eight full days. The mechanism is very good quality in that it is jeweled and the gearing is gold plated. The balance wheel escapement means that this clock will continue to run while being moved. The vertically fitted micrometer is positioned on the front of the dial. The Maker’s name and serial number are die-stamped on the backplate. The serial number is “597417.” This indicates that it was made sometime around 1955.

This case is constructed in bakelite. Bakelite is a phenolic resin. The Chelsea Clock Company originally transitioned to this product during World War II due to the war time shortage of brass. The use of bakelite turned out to be a suitable product for the intended use of this type of clock. The bezel is the hinged. It opens from the right allowing one to access the dial. It is secured tight with a small .5 inch knurled screw knob fastener. The back of this case is also has the Chelsea Clock Co. name embossed into it.

This clock was a commericailly used product. As a result, it has experienced some wear to the dial which measure 8.5 inch diameter and is cataloged as a Type A. It features a 24-hour time ring and is marked “Chelsea Clock Co. / Boston.” It is also marked “U.S. GOVERNMENT / SER. No.” The dial is in black enamel and this contrasts with the white numerals, non luminous enamel spade hands and silver painted sweep second hand.
