Pre-owned CWC watches

CWC, or Cabot Watch Company, is a British watch manufacturer founded in 1972 by Ray Mellor, former director of Hamilton UK. At a time when many Swiss brands were stepping away from military contracts, CWC emerged as the main supplier of watches to the British Armed Forces. From the outset, the brand was commissioned by the Ministry of Defence (MoD) to produce timepieces meeting the strict specifications of military personnel — combining toughness, accuracy, and exceptional legibility under all conditions.

The brand's first iconic model was the CWC W10, a simple yet highly dependable mechanical watch designed for British Army soldiers. Powered by a hand-wound ETA movement, the W10 stood out with its clean dial, luminous indices, and sturdy stainless steel case. CWC followed with other noteworthy models, such as the 1980s RAF chronograph, driven by the Valjoux 7733 calibre, and the Royal Navy Diver, developed for British combat divers — initially as an automatic, later as a quartz version.

The quartz revolution marked a major turning point for CWC, with the release of the now-famous G10 in the 1980s. This no-nonsense, ultra-durable quartz watch was widely issued to British military personnel for decades, becoming one of the most recognizable military watches of its time. Used by elite forces such as the SAS and SBS, the G10 has become a true icon of functional watchmaking.

Staying true to its military roots, CWC has never chased civilian trends. It maintains a discreet production strategy focused on utility, dependability, and strict adherence to military standards. This unique positioning makes CWC a favourite among military watch enthusiasts, collectors, and those who appreciate authenticity and rugged heritage. Vintage models, especially those bearing period-correct MoD markings, are highly sought-after on the pre-owned market.

Even today, CWC continues to manufacture its historic models, including the RN Diver Automatic and the G10, for a discerning audience drawn to military authenticity and legacy.
