CHELSEA Timemaster Clock
The 6" Timemaster Quartz Radio Room Clock by Chelsea (Model 40101) A rare opportunity to own a Chelsea special, non-catalog Government/Commercial clock. New, factory fresh in an unopened, factory sealed box. The Chelsea Timemaster is the pinnacle of maritime timekeeping - and this model features a Radio Room dial. This clock has been used for many years by the United States Navy in the demanding shipboard environment - setting the standard long before satellites were used for navigation - and still in use today. This Chelsea Timemaster has a silent, high precision quartz movement as specified by the U.S. Military. It meets standards for vibration, temperature and humidity extremes. The accuracy of this quartz movement is +/- 1 minute per year. The Chelsea Timemaster clocks have passed U. S. Navy tests for accuracy, shock, vibration, temperature and humidity extremes. The sinking of the Titanic resulted in the Radio Act of 1912 that required 24-hour radio watches. The disaster also led to clocks in the newer radio rooms featuring three-minute periods marked in red. That three minutes provided a silent period when only emergency radio messages could be transmitted. These clocks had an extra hour hand which was set on local time; the regular hands were set at Greenwich mean time (Zulu) since all incoming and outgoing messages were so marked. The red segments radiating out from the center post designated 3 minute periods at the quarter and three-quarter hours to observe radio silence to listen for emergency broadcasts on 500kcs. Later models featured additional green sectors at the top of each hour and 30 minutes past each hour for the monitoring of the 2182kcs. distress frequency. The red marks in the chapter ring designated 4 second intervals to time emergency autoalarm signals used to activate alarm bells on nearby ships and shore stations during the sending of an SOS. The Timemaster is suitable for use on the enclosed bridge, wheelhouse, and ships radio room, on any Government, Commercial or Pleasure vessel or of course, in any home. Timemaster is not included in the Chelsea catalog.
