Founded in 1897, Chelsea Clock Company is one of the oldest, and largest clock manufacturers in the United States. The company continues to manufacture and repair clocks at its original corporate headquarters in Chelsea (MA). The Patriot Deck Clock is a reproduction of Chelsea Clock’s original WWII-era Navy engine room clock. Made to the same mil-specs issued by the US Government in the 1940s; case fabricated from black phenolic resin (like Bakelite). White or black dial. Easy to see military time stamps. Just found these - kinda cool. For the man who has everything territory.
