Unlike other replica sector clocks, these models offer a superior build and distinct style. If you're looking for something beyond the typical wall clock, this piece is perfect. It makes an excellent conversation starter for an office, workshop, garage, reception area, and more. Our images show two original clocks from RAF sector rooms and a clock from World War II, which inspired this model.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eOriginally known as \"colour change clocks,\" sector clocks were introduced by the RFC (Royal Flying Corps), the predecessor to the RAF, during World War I in 1917. They were used to track the movements of German planes and airships, evolving further during World War II. These clocks gained prominence during the Battle of Britain and remained in service on certain air force bases through the Cold War. Today, original sector clocks are highly prized, often selling for £5,000-£8,000 ($6,500-$10,500) at UK auctions.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eDuring the war, several versions of sector clocks existed, each with slight face variations but retaining the iconic red, blue, and yellow triangles. The clocks were either electrical or mechanical. This MWC clock replicates the original electric version and includes a sweeping second hand for authenticity.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eHow Sector Clocks Were Used\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eThe sector clock was essential in Ground-Controlled Interception (GCI) before modern airspace control systems existed. The clock face features red, yellow, and blue triangles in five-minute intervals, with both an outer 12-hour ring and an inner 24-hour dial.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eWhen an aircraft was sighted, its position was recorded alongside the triangle color under the minute hand at the time. This data was then relayed to sector headquarters, where color-coded markers represented each air raid on a large map of the UK, overlaid with a British Modified Grid. As aircraft formations moved, these markers were adjusted with magnetic \"rakes.\" This method enabled Fighter Controllers to track movement and predict possible targets quickly. The color coding also conveyed the age of the information, supporting rapid and effective response decisions.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eSpecifications\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eSize: 30.5 cm (approx. 12 inches)\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eMaterial: Durable polycarbonate\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eMovement: Silent, accurate quartz with a sweeping second hand (no ticking noise)\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003ePower: Includes one AA battery\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eThese sector clocks not only capture historical significance but also offer a stylish, high-quality timepiece for any setting.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eClock in stock and ready for fast despatch\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003ePrice £34.95 with free UK delivery\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eViewing \u0026amp; Collection is welcome (appointment only)\u003c\/p\u003e","brand":"MWC Military Watch Company","offers":[{"title":"Default Title","offer_id":54599709163788,"sku":null,"price":34.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/3517\/6716\/files\/s-l1600_0551793e-d73e-4227-a291-1c34c907a86a.webp?v=1766085877","url":"https:\/\/healysoutletstore.co.uk\/products\/mwc-g10lm-50m-date-window-2025-military-watch-army-green-strap-copy","provider":"Healys Outlet Store","version":"1.0","type":"link"}
