CWC G10 Quartz - British Royal Navy 'Fatboy' - Issued 1985


An Iconic Royal Navy Marked 0552-6645 Watch. The Cabot Watch Company G10, Last of the Fatboy Case Iteration, Issued in 1985 - in Fantastic Condition.

The quartz "G10"  was the first quartz watch supplied to the British military, with the name coming from the form G1033 that had to be filled in, in order for you to be issued one. The G10 dial was designed for simplicity and clarity and CWC supplied over 160,000 of them to the MOD for 26 years between 1980 and 2006, many with different caseback markings denoting the specific Armed Force the watch was issued to!

The old logo was used for a couple of years and was changed to the oval logo in 1982. The early G10s were nicknamed Fatboy as the case was thicker than the current models in order to house more significant movements. Here, the 1985 example offered for sale is a Fat Boy iteration and houses the ETA 555 movement. 1985 was the last year of production of this case variant of the G10.

What’s On Offer 

At over 35 years old, this watch is in absolutely remarkable condition. The stark black dial looks tremendous against the contrast of the bold white Arabic numerals which are immaculate. The luminous indices have also survived well and are an attractive vanilla hue as is the lume on the pencil hands. A needle central seconds hand, CWC signature, and Tritium emblem complete the dial, encapsulated underneath robust Plexiglas and encased in stainless steel. The case back is engraved: 0552/6645-99 5415317 12284/85. The watch case is also in fine fettle with only minor signs of general wear. An iconic reference with military significance, a fantastic addition to any collection. We come across less and less of these as each year goes by, so don't wait around and end up missing this one!
