Introduced in 1980, the CWC “Fatboy” is a distinctive military-issue watch made for the British Ministry of Defence. Its nickname comes from the thick stainless steel case required to house the early ESA 536.121 quartz movement. Produced between 1980 and 1983, the Fatboy was issued to all branches of the UK Armed Forces, including the Army, Royal Navy, and RAF. Known for its fixed strap bars, acrylic crystal, and tritium lume, it represents the rugged, functional design of Cold War-era military timepieces. Today, the Fatboy is prized by collectors as a rare and authentic piece of British military history

What's on offer

This original CWC “Fatboy” from circa 1982 is a superb example of British military watchmaking, prized for its rugged reliability and distinctive design. The black dial with crisp white numerals ensures excellent legibility—vital for military use—while the robust stainless steel case, with its thicker profile that inspired the “Fatboy” nickname, carries the expected dings and marks of service. The unmarked caseback and acrylic crystal also display honest wear, testament to decades of faithful duty.

Fitted with a NATO-style strap and fixed bars, it retains its authentic military aesthetic while offering comfort and practicality. Despite its vintage scars, the watch is in very good condition overall, embodying the durability and no-nonsense spirit that made it a trusted companion for British forces during the Cold War. A true piece of military history and a worthy addition to any collection.
