CWC Cabot Watch Company G10

Cwc g10.jpg

In 1980, the first quartz watch issued to the British Forces was made by CWC. The old logo was used for a couple of years and was changed to the oval logo in 1982. The early G10s were nicknamed the Fatboy as the case was deeper than the current models due to earlier deeper movements. The G10 is still as rugged, reliable, accurate and dependable as it has always been.

Features:

  • Acrylic glass.
  • Water resistant to 5 ATM.
  • Battery hatch for ease of replacement.
  • 38mm case incl. crown, 36.5mm without crown
  • First issued 1980 with thousands in service.
  • Swiss-made using Swiss parts to British military specification.
  • Quartz ETA 955.102 movement.
  • Fixed bars, supplied with NATO issue 18mm strap.

Cabot Watch Company supplied the G10 from 1980 and was contracted by the MoD until recent times. A conservative figure of over 200,000 G10 watches have been produced for the military, based on 10,000 per year over a 28 year period. 22,000 were supplied to the Royal Navy in 1991.

The CWC quartz G10 (6645-99-5415317) was issued between 1980 and 2006 but not in 86, 92, 93, 94, 96, 99, 00, 01, 02, or 03.

The 1980 had no service prefix.

Note: observed a small number of 1985 watches which appear to have a very similar dial to the late issue 1984 and eta 555.412 movement. To date have been unable to confirm if these are as originally manufactured, or in service repairs, or later post service parts 'Frankenstein's'.

1987 Manufacturer – CWC Manufacturing details – subtle change to the style/finish/texture of printing on the dial and thinner backplate. Movement – eta 555.115 Service – 0552 Royal Navy Known S/N range – 15917 / 22970

1988 Manufacturer – CWC Manufacturing details – as 1987 but change in movement during early production Movement – eta 555.115, or eta 955.114 Service – 0552 Royal Navy Known S/N range – 23958 / 27828

1989 Manufacturer – CWC Manufacturing details – change to the style/finish/texture of printing on the dial and Swiss Made now on bottom of dial Movement – eta 955.114 Service – 0552 Royal Navy Known S/N range – 28035 / 52077

1990 Manufacturer – CWC Manufacturing details – change again to the style/finish/texture of printing on the dial and style of stamping on backplate changes from approximately S/N 61000 onward. Movement – eta 955.114 with updated/improved circuit board Service – 0552 Royal Navy Known S/N range – 52474 / 74036

1991 Manufacturer – CWC Manufacturing details – pretty much as initial 1990 production Movement – eta 955.114, or 955.102 (appears somewhat randomly fitted from approximately S/N 77000 onward). Service – W10 British Army Known S/N range – 74125 / 82076

1995 Manufacturer – CWC Manufacturing details –initial production pretty much as 1991. Later issue have a change to the style/finish/texture of printing on the dial and the eta 955.112 movement becomes more common. Movement – eta 955.102 or 955.112 Service – 0555 Royal Marines Known S/N range – 0021 / 4848

1997 Manufacturer – CWC Manufacturing details – pretty much as initial 1995 production. First few hundred issued have etched rather than stamped S/N’s, along with the pheon and service prefix (above the NSN). Also early stamped S/N examples are missing the forward slash between the S/N and year. Movement – eta 955.102 Service – W10 British Army Known S/N range – 0140 / 5214

1998 Manufacturer – CWC Manufacturing details – pretty much as 1997 production. Again, first few hundred issued have etched rather than stamped S/N’s and service prefix (above the NSN). Movement – eta 955.102 Service – W10 British Army Known S/N range – 0003 / 7416

2004 Manufacturer – CWC Manufacturing details – Initial issue pretty much as 1998 production. Again, first few hundred issued have etched rather than stamped S/N’s and in most instances, this etched S/N is above the NSN. Further some of the initial issue have traditional backplates others have water resistance details in both ATM and Feet stamped at the bottom of the backplate. Later production with stamped S/N’s this water resistance information becomes standard but in smaller font and ATM measurement only. Also, there are again subtle changes to the style/finish/texture of printing on the dial in these later watches. Movement – eta 955.102 Service – W10 British Army Known S/N range – 086 / 2938

2005 Manufacturer – CWC Manufacturing details – pretty much as later 2004 production. Movement – eta 955.102 Service – W10 British Army Known S/N range – 0093 / 6000

2006 Manufacturer – CWC Manufacturing details – change to texture and colour of dial tritium markers. Movement – eta 955.102 Service – W10 British Army Known S/N range – 0021 / 9348
