A genuine British Army–issued CWC W10, the mechanical general-service field watch carried by British servicemen and now one of the most collectible everyday military watches of its era. This is an original vintage issue, not one of the modern CWC reissues, wearing all the correct military markings: the broad arrow (property of the Crown), the W10 Army designation, the NATO stock number 6645-99-523-8290, and the individual issue number 808 engraved on the caseback. CWC — the Cabot Watch Company — was founded in 1972 by Ray Mellor, formerly Hamilton's contracts director, to take over British military watch supply when Hamilton withdrew during the quartz crisis. Using the same Swiss suppliers, CWC continued the W10 essentially unchanged but for the name on the dial. Inside is the hand-wound ETA 2750: a 17-jewel, 21,600 vph manual calibre with hacking seconds, which stop the running seconds for precise time-setting against a signal — a military requirement. The case is a monocoque, one-piece construction in non-magnetic stainless steel with fixed lugs, opened only from the front by lifting the crystal. By the early 1980s the quartz G10 had taken over general-service supply, which makes the mechanical W10 effectively the last of the hand-wound British Army field watches — the end of a line running back through Hamilton and Smiths to the Second World War. The dial is textbook W10: matte black with crisp white Arabic numerals, a dotted minute track, a luminous triangle at twelve, the CWC logo and circled T (denoting tritium) above the hands, the broad arrow below, and SWISS at the foot. Roughly 35mm across with 18mm fixed lug spacing and an acrylic crystal, it wears as a compact, honest tool watch. Condition is exactly what you'd hope for from a watch that saw service: properly patinated, not restored. The tritium plots and hands have aged to a warm cream-and-brown tone and, as with all forty-plus-year-old tritium, no longer glow — expected, original, and never relumed. The dial carries light age spotting and the case shows the knocks and softened edges of real use. Nothing has been polished out or tidied up; it is an unmodified, original example with genuine military character. Offered as watch only — no box or papers. Shipped fully insured and tracked.
