Catalogue description
Dealer description — Craft & Tailored
Cabot Watch Company or CWC was founded in 1972 with a clear focus in mind, to win MOD wristwatch contracts. CWC is most known for creating the military diving watch that replaced the Rolex 5517 or Rolex Milsub for the British military and continued to supply military spec wristwatches to different branches of the British and European Militaries until the 1990s. During the 1970s the CWC, Hamilton, Precista, and Newmark were contracted by the British Ministry of Defense and Royal Navy to provide them with pilot's chronographs under the ordinance DEF-STAN 66-4 which specified all chronographs be outfitted with start, stop and reset pushers. The Valjoux Cal. 7733 chronograph movement was selected for these applications for its reliability and accessibility of parts. Sterile dials are some of the most coveted and interesting watch variants for military issued watches to possess. "Sterile" simply meaning lack of the logo on the dial and/or the military markings on the case back, this was done to reduce the exposure of information in the event that the soldier was captured. It is commonly known they were reserved for the units involved in the most covert and secretive operations.

Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide
Chronographs and split-seconds watches
A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.
Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.
What to look for
- Push-pieces on the case band or a single button in the crown (monopusher).
- Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
- Column wheel versus cam control visible in the movement.
- Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).
Dating clues
- Pocket chronographs with heart cam reset: after 1862.
- Wrist chronographs: from c. 1910; two-button designs from the 1930s.
- Automatic chronographs: from 1969.
