The sinking of the Titanic resulted in the Radio Act of 1912, requiring 24-hour radio watches at sea. The disaster also led to a clock design featuring two 3 minute periods marked in red to mark a silent period when only emergency radio messages could be transmitted. Two green markings designate silent periods during which time one would listen for coastal distress signals. Over the years Chelsea has produced thousands of these types of clocks according to US government specifications for use aboard military vessels. Case is custom made from phenolic, a durable heat resistant resin designed to last for decades. Dimensions: 7 5/16" Dia x 2 3/8" Depth Weight: 1.5 lbs
