We also undertake case refinishing to CWC’s specification. This work is carried out by our fully trained polishing team using our state of the art polishing department.

It is recommended by CWC that their quartz watches receive a battery service every couple of years and all watches receive a complete service every 5 years. However, if the watch is a diving or water resistant model and used in water they also recommend the water resistance of the watch is tested on an annual basis.

A Brief History of CWC

The main servicing procedure

  • A Complete Service involves the watchmaker checking the watch’s functions, diagnosing the cause of any faults.
  • Once the case is clean it is reassembled with new seals and gaskets, which are lubricated as required with special greases. The case is now ready to receive the cleaned movement.
  • All parts are then cleaned in a series of ultrasonic chemical baths which removes all the old oil, grease and dirt.
  • While the movement is being cleaned the case will be completely broken down (case back, bezel, crystal, pushers etc. removed) and, having removed all the seals and gaskets, refinished and cleaned in large ultrasonic tanks.
  • Once the case is clean it is reassembled with new seals and gaskets, which are lubricated as required with special greases. The case is now ready to receive the cleaned movement.
  • The cleaned movement and pristine components are systematically reassembled and lubricated using up to 8 different fine synthetic oils and greases, before having the dial and hands refitted.
  • The watchmaker will now reset the clean movement with the dial and hands mounted into the watch case ensuring there are no hairs or dust in the case and recheck the watch regulation on the timing machine.
  • Once the case is closed the watch is then tested for water resistance and the final aesthetic, timekeeping and power reserve checks are made to ensure the watch is performing correctly.

Battery service

  • The watch is opened and electronic components checked using specific testing equipment.
  • Replacement of the battery and gaskets as appropriate to the watch model.
  • Tested for water resistance. Final aesthetic and timekeeping checks to ensure the watch is performing correctly.

We reserve the right to invalidate the warranty if repairs are performed by persons not authorised by us to take such action. Provision of the warranty will be free of charge. We will decide in our absolute discretion whether provision of the warranty will be in the form of a repair or the replacement of a part of the watch.

Thank you to the team for the servicing and refurbishing of my fathers' Omega watch. The accuracy is well within original factory tolerance and refurbishment makes it look as good as new. Thank you also for the tour of your workshops when I collected my watch.

Brief history of CWC Watch Service

The Cabot Watch Company was established in 1972 purely to produce military watches for HM Forces.  Their first watches were the GS Navigator and the Pilots’ asymmetrical chronograph, both with mechanical movements, which quickly established CWC as a reliable, durable watch in the UK military world.

In 1980, CWC supplied the first quartz watch to HM Forces, the G10 Quartz nicknamed the ‘Fatboy’ due to the thickness of the case.  In the same year CWC won the contract to supply a milsub to replace the Rolex Submariner as the Royal Navy Divers’ watch.  The 1980 Royal Navy Diver Automatic is probably the rarest milsub to date.

The CWC logo was originally a simple typeface which was changed in 1982 when the oval logo we know today was introduced.

In 1982/3, the quartz version of the CWC Royal Navy divers’ watch was issued and it remained the watch of choice to the Royal Navy well into the new millennium.  In 1987, the MOD requested CWC to manufacture a new watch, the black Special Forces RM SBS issue quartz 300m divers’ watch.  Throughout the 90s and well into the new millennium, CWC supplied the MOD with thousands of G10 watches for the British Army and Royal Navy. The GS2000 began service with the RAF in the year 2000 and were issued through to 2003 before being superseded by the G10 GS being a more streamlined version of the original ‘Fatboy’ with the addition of a date.

Today, CWC continues to supply watches and straps to HM Forces as well as aircraft and ships’ clocks and stop watches.  Many older CWC watches still survive, having seen military service, a true testament to their durability. Some CWC watches are now becoming rare and collectable, such as the 1980 CWC G10, because of their strength, durability, clarity, precision and functionality.
