Original sector clocks are very rare and can cost up to £4,000. This excellent replica of the famous RAF Sector clock has been handmade made in England to the highest standards. The case is of solid wood, based on the original style, stained and lacquered with a rich dark mahogany finish and has a real brass bezel and glass. The clock is fitted with a quality quartz movement and spade style hands as the original clocks. This is a very substantial wall clock measuring approximately 291 mm in diameter (over 11.5").
The Clock in Use
All incoming reports of enemy aircraft approaching which were received from outlying observation posts would be colour coded with flags of either red, yellow, or blue according to the time they were received. These colour-indicated times were assigned according to the position of the minute hand on the special Operations Room Clock, the dial of which had painted triangles of red, yellow and blue, at five minute intervals around the dial. The colour indicated by the minute hand at the time the report was received would be the colour given to the message and plotted on the Operations Room map. In view of the speed of the enemy raiders crossing Britain's coastline the RAF's response had to be made in minutes. This colour coding process and the elaborate communications network behind it created a highly effective and efficient system. It was possible to have fighters in the air and on their way to an intercept within five minutes of the initial sighting. Without the simple time coding system devised by the RAF, the British might not have been so successful in holding control of the skies over Britain during the crucial Battle of Britain as well as later in the war. It is believed that such clocks were in use from around 1935 to the early 1950s.
