This Watch We have here a classic W10 military watch, from the first year that Hamilton produced these for the Ministry of Defence. The monocoque, tonneau shaped, stainless steel case back is engraved '523 8290, W10 6645 99, 4972 73' and also has the Broad Arrow. It has fixed lugs, as with all military watches, and houses a manual wind cal. ETA 2750 with hacking seconds. The black dial is one of the best examples we have seen and the case is looking to be untouched. It's a really sharp example! The dial is signed with 'Hamilton', the 'Circle T' (for the Tritium lume) and with the Broad Arrow. The lume on the hour indices markers and hands are in good order. Extra Points The Hamilton Watch Company is a Swiss manufacturer of wristwatches, based in Bienne, Switzerland. Founded in 1892 as an American company, Hamilton Watch Company ended American manufacture in 1969. Hamilton produced W10 watches for the British Military between also in 1973 and 1976, and it is estimated that around W10 pieces 30,000 were produced during these three years. Hamilton took over the contract from Smiths, and were succeeded by CWC. It was, however, during the early 1900s that Hamilton were named the official watch supplier for the American Armed Forces and they produced watches for the USA not only throughout both World Wars, but also for every military operation that the USA have been involved in over the last 100 years. Through a series of mergers and acquisitions, Hamilton eventually became integrated into the Swatch Group, the world's largest watch manufacturing and marketing conglomerate. The watch has been fully serviced by our on site workshop and comes with a 12 month, non waterproof service cover. What we think Hamilton produced W10 watches for the British Military between 1973 and 1976, and it is estimated that around 30,000 were produced during these three years. Hamilton took over the contract from Smiths, and were succeeded by CWC. There is something truly amazing about wearing a military watch, never knowing what it may have seen or been through throughout its life, whose wrist it was on etc That is what I think people are drawn to with military watches the unknown, but the potential.
