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. Produced under
various contracts which offer limited availability to the civilian
