It is reported that these instruments were used by observers in Beaufighters and other nightfighters during WW II for reconnaissance including U-boat spotting.

RARE, WW2 ‘Dirty Dozen’ 15 Jewel Swiss Omega British WD Wrist Watch With Correct Military & Manufacturer Markings & Later Wrist Strap. Sn 16357 - 16357
In the 40s, during World War II, Britain’s Ministry of Defence (MOD) needed watches to issue to army personnel – they felt civilian watches just didn’t quite make the mark. Perhaps in a bid to maximise production, rather than partnering with a specific brand, they invited Swiss manufacturers who could build a watch to the requested standard to bid for contracts. Due to the rigours of military life, very strict specifications were set, and all in, twelve watch manufacturers were eventually accepted, resulting in the nickname ‘The Dirty Dozen’. They were: Buren, Cyma, Eterna, Grana, Jaeger Le-Coultre, Lemania, Longines, IWC, Omega, Record, Timor and Vertex. These were all delivered in 1945 and accompanied by a pigskin or canvas strap. More formally, these watches were known as W.W.Ws, a code established by the British Army to distinguish these from other military equipment and it simply stood for Watch. Wrist. Waterproof. The MOD specs were exactly what you would expect a military watch to be - waterproof, luminous, regulated to chronometer level and composed of a case that was rugged. Two serial numbers were required, one being the manufacturer’s number, and the other (with the letter) being the military store number. On top of that, the dial needed to be black, with arabic numerals and sub seconds in order to maximise legibility. The case-back had to include the W.W.W designation and a broad arrow marking, with the dial only displaying the latter. This is a rare, original, WW2 British Military watch by the quality Swiss manufacturer Omega, one of ‘The Dirty Dozen’. The watch has all of the correct WD features listed above and has crisp Omega and WD markings together with 15 jewelled movement and compensated balance wheel (all markings illustrated). The watch is unrestored and has the correct steel pins and removable screw back. It is fitted with later expanding metal bracelet over the original pins. The glazed face is 36mm diameter. The watch has been inspected and is in fully working order. The price for this rare WW2 British Military Omega watch includes UK delivery. Sn 16357
