CWC Royal Navy SBS Diver 0555/6645-99-7995443, 1993

Dealer description — Craft & Tailored

Founded in 1972, Cabot Watch Company (CWC) was established with the goal of producing purpose-built military timepieces for the British Ministry of Defence. Over the following decades, the company became one of the MOD's principal suppliers, manufacturing wristwatches for a variety of British military branches and earning a reputation for rugged, purpose-built tool watches designed for operational use. Developed in response to a new Ministry of Defence specification introduced in 1987, the CWC SBS Diver was built to meet the operational requirements of the Royal Navy's Special Boat Service (SBS), one of the world's premier maritime special operations units. Designed as a true military dive instrument with a 300-meter depth rating, the SBS specification featured a nonreflective black PVD-coated case to reduce glare in low-light environments, along with a practical day-date display to assist personnel during extended deployments. Watches produced to this specification carry the military NSN 0555/6645-99-7995443 , distinguishing them from the earlier Royal Navy dive watch contracts. The first SBS divers entered military service in 1988 and were fitted with acrylic bezel inserts, echoing the construction of the contemporary Royal Navy divers. In 1992, the specification evolved to a metal bezel insert featuring a distinctive, wide hash-mark design unique to that contract year. Later production examples, including this 1993-issued watch, adopted the now-familiar narrow hash-mark metal bezel insert, a configuration that would remain standard on subsequent SBS issue watches. This example dates to the 1993 contract , the first year to carry the Royal Navy purchasing code 0555 in place of the earlier 0552 designation. Research published by CWC Addict indicates that approximately 100 examples were issued during the 1993 contract. In addition to their service with the Special Boat Service, watches from this period also saw use within other United Kingdom Special Forces elements. Combined with their documented military provenance, specialist operational history, and limited production, early SBS divers have become some of the most desirable modern British military wristwatches.

DIAL & HANDS The original matte black dial remains in excellent condition, free from any notable degradation or marks. The tritium lume on both the dial and hands has aged evenly to a rich yellow coloration.
