SKU Code: CLK/WDN/SKTR

Introducing our high-quality replica sector clocks, encased in robust wood with a distressed/aged dial and genuine glass. These clocks offer a distinctive alternative to ordinary wall clocks and are sure to be a conversation starter in any office, workshop, garage, or reception area. The design is inspired by original RAF sector clocks from World War II, as seen in the reference images of an RAF sector room and an original clock from the period.

Historical Significance:

Originally known as "colour change clocks," these timepieces were introduced in 1917 by the Royal Flying Corps (RFC), the predecessor of the RAF. They played a crucial role in monitoring the movements of German planes and airships during World War I and were further developed during World War II. The clocks became iconic during the Battle of Britain and continued to be used on some air force bases through the Cold War. Today, original clocks are highly sought after, often fetching between £5,000 and £8,000 ($6,500 to $10,500) at UK auctions.

Design and Features:

Various versions of the clock existed during the war, each with slight variations in face details. However, all featured the distinctive red, blue, and yellow triangles and were either electric or mechanical. Our MWC replica includes a sweep second hand, replicating the original electric version.

Usage:

The Sector Clock was a vital component of Ground-controlled interception (GCI) before modern computerized airspace control systems. Its face is marked with five-minute red, yellow, and blue triangular segments, an outer 12-hour ring, and an inner 24-hour dial. Aircraft positions were recorded along with the color of the triangle beneath the minute hand at the time of sighting, and this information was relayed to sector headquarters. Counters representing each air raid were moved across a map of the UK, enabling Fighter Controllers to quickly assess the formation and direction of enemy aircraft. The counter color indicated the age of the information, allowing for swift and effective decision-making.

Specifications:

• Case: Strong and robust wooden casing
• Dimensions: 35.56 cm (14")
• Movement: Highly accurate silent quartz movement with sweep second hand
• Power: 1 x AA battery (supplied)

This clock comes ready to use with an AA battery included, ensuring silent operation free from the annoying ticking sound typical of most quartz wall clocks.

Choose our sector clock for a blend of historical charm and modern reliability, perfect for adding a unique touch to any space.

Installation Note:

To avoid breakage, ensure the clock is securely mounted. We recommend using a screw and Rawlplug on a brick or concrete wall. For wood surfaces, a screw can be used directly.
