Rare Model 22, 2-day Deck Watch with English wartime markings, circa 1943.
Large screw back and bezel Keystone base metal case with snap-on inner dome, the rear cover not with its usual United States markings but engraved for its English use 'HS^2' (Hydrographic Stores type 2: Deck Watch). 35-size, 21 jewel, nickel barred movement with safety hand setting device, the barrel bar engraved 'Adj to Temp & 6 Pos.' Double-roller detached lever escapement, paired with Hamilton's monometallic 'ovalising' balance and matching balance-spring made of their specially developed 'Elinvar Extra' material. Silvered metal dial with 48 hour up/down sector, original blackened steel hands. Watch 71 mm diameter and weighing just over 11 ounces. Together with original Hamilton 2-piece box, 15 x 12.5 x 5 cm.
Hamilton Watch Company, Lancaster, Pennsylvania - see the books by Marvin Whitney for the extraordinary history of how this company developed both a Model 22 lever escapement Deck Watch and the Model 21 box chronometer at the outset of the USA entering the Second World War. The Deck Watch came in two forms, in a pocket watch-type case, as here, and also set-up as a box chronometer in a brass bowl held in gimbals.
NB: This pocket watch form is my favourite of all Hamilton's wartime production and is a most tactile, transportable and accurate master time source, and this is one of the rare examples carrying English wartime markings.
The watch showing some signs of use, no doubt from its wartime action, and the original plastic 'ub' crystal with stress cracking, otherwise in good original condition. New/old stock crystals are available and the dial itself is in good clean condition, as is the box which has never been fitted with Hamilton's usual hand setting label. Winding and working well, but not serviced by me and priced accordingly.
