Screw front and back ’STAYBRIGHT’ stainless-steel case. Longines 16-jewel calibre 19.71N gilded movement bearing their number in full: 5759859 as well as the B&Co (Baume & Co) importers stamp. Straight-line detached lever escapement with polished steel club-tooth escape. Compensation balance, balance-spring with overcoil. Signed enamel dial, also bearing the ‘Broad Arrow’ mark, as does the movement, the rear of the case also bearing the Hydrographic Stores nomenclature and the number 3 standing for Deck Watch. Together with its original strong 2-piece composite material box. Watch 52 mm diameter, box 9.5 x 7.5 cm.
Longines, St Imier, Swizerland, one of the most venerable Swiss companies, and with one of the longest traditions of providing best quality Swiss watches, both pocket and wrist, for the English market – thus the gilded rather than nickel finish to this movement. They have a long association with Alfred Baume & Company who were their main importers into England.
NB: The International Chronometers Index held at Greenwich Observatory may hold records of this watches wartime service, but many records of the Swiss supplied instruments were sadly destroyed.
Some damage to the dial caused by the dial foot at 10, including a small local repair. Otherwise in fine original condition, including its box which rarely seem to survive. The watch not cleaned by me but presently performing well, but it can be freshly serviced if required – my likely cost around £200. Please note this watch was photographed prior to cleaning.
