Chelsea Clock Co., Boston, Mass. A Type B Model 12E Deck/Engine Room Clock in a black resin case.

This model was originally marketed for use in an engine room or for use on the deck of a boat. Today, we sell a fair number of these to customers that use them in various home settings. The kitchen or the bathroom are the two most popular mounting locations today.

This fine clock was made by the Chelsea Clock Co., in Boston, Massachusetts. It was made for use by the U.S. Government. The phenolic or resin case is black in color. It features a rear mounting flange and a hinged bezel. The bezel is fitted with glass and is secured with a large screw against a rubber gasket. This case is somewhat water tight. The black dial measures nearly 5.5 inches in diameter. The time ring, Maker’s name and “U.S. GOVERMENT” are pressed into the surfaced and highlighted with white paint. All of the numerals are displayed in an Arabic format. The hour and minute hand is painted white. The sweep seconds hand is presented in red. The method for making time adjustments is by the use of a micrometer located just inside the 2:30 position.
