The Patriot Deck Wall Clock is an authentic reproduction of Chelsea Clock's original WWII era navy engine room deck clock. The original Deck clock is found on thousands of navy vessels today with a history dating back to the early 1900s. The Patriot deck clock's case is custom made from phenolic, a durable, heat resistant resin designed to last for decades. The Patriot Wall Clock features time displayed in a classic 12/24 hour military format. The Patriot Deck clock has a sweep second hand that allows for a more precise time display. Featuring a clear glass lens, its hinged bezel and brass screw-bolt lock offer easy access for adjustments. Includes individual, hand-applied serial number, registered in Chelsea's manufacturing log. The Patriot Deck Wall Clock is a companion piece to the Patriot Deck Barometer, the Radio Room Clock and Patriot Deck Tide Instrument.
