Stores reference 6B/234, (originally 6B/159). In 1940 the Air Ministry began to issue 'economy' (brand-less) watches to be used where the usual Longines and Omegas could not be justified. These were built to the same high specification with a Dennison case, 16 jewel Swiss movement and a white dial. Engraved on the back with A.M. markings and reference codes 6B/159 indicating a pilot's/navigator's watch. However, this number has been 'overscribed' and replaced with '234' indicating the watch has been repaired and re-issued during the war (some watches were issued solely as 6B/234's indicating a subsitute standard pilot's wristwatch).
This example is in reasonable condition. The case is good showing only fairly minor scratches and wear. It is clearly marked to the back cover with a 1940 date code and has matching serial numbers on both case and rear cover. The white dial has black numerals and a chapter ring marked at 5 second intervals betwen 5 and 55. Black hands and sweep seconds hand. The dial is a bit discoloured/marked and the crystal has some light scratches. Non original black nylon strap. The watch ticks strongly and keeps accurate time. A considerably cheaper way of obtaining a genuine early war period pilot watch. Quite good overall condition. Stock code C23313.
