Description
Following the sinking of the Titanic, the U.S. Congress mandated 24-hour radio watches for all coastal stations and vessels at sea. It also designated three-minute “silent periods” for voice and radio transmissions, when only safety and emergency signals were permitted. The Radio Room Clock is a fully functional timepiece that makes it easier to observe the silent periods.
Chelsea Clock based its Radio Room clock on WWII-era engine room clocks. The red sectors on the dial indicate Morse Code silence and the green sectors are for voice transmission silence. Red bars around the outside are for timing the official ITC alarm signal. In addition to the black hour, minute and second hands, there is a white “Zulu” hour hand for setting to another time zone. A heat-resistant black phenolic resin case matches the design and durability of the Naval Deck Clock. The clock features an accurate quartz movement, so no winding is required.
