Battle of the Legends: CWC G10 Vs. CWC G10 Fatboy-80

July 14, 2023 5 Comments

From serving military personnel, veterans and collectors, the G10 series has generated immense interest over the years. Today, we delve into a historic comparison between the classic CWC G10 and the CWC G10 Fatboy-80, which is the re-issue of the legendary predecessor that started it all, the CWC G10 'Fatboy' from 1980. Join us on this horological journey as we explore the remarkable story that makes these watches an absolute must-have for any discerning military watch enthusiast.

The G10's story began in the late 1970s when a shift occurred from mechanical to quartz timekeeping technology. The Defence Standard DEF STAN 66-4 (PART 4) /4 was issued on 29th February 1980, a leap year day, and preserved the tonneau case shape of the mechanical W10 watch while featuring the word 'Quartz' on the dial. However, a pivotal decision led to the adoption of a more rounded case for the actual watch that was issued later. Ray Mellor, the founder and a key figure in the development process, proposed a different case shape, believing it to be more suitable for the quartz design. The change was embraced and thus began the legend of the G10 in its new form. This decision would shape the future of the G10 series.

Let's start with the origins of the CWC G10 'Fatboy', the trailblazer that paved the way for the iconic G10 collection. Introduced in 1980 as the 'G10 watch', it was the very first quartz watch issued to the British forces under the NATO Stock Number 6645-99 541-5317 which remains the same to this day. The watch quickly garnered worldwide acclaim. Collectors and enthusiasts affectionately coined the name 'Fatboy' for its fat/deeper case to house the early ESA 536.121 Swiss movements, which were notably thicker than today's ETA Swiss movements. As the movements reduced in depth due to advancing technology, the case of the G10 grew thinner, progressing to the 'Medium Fatboy' in 1983, but that's a story for another day.

The CWC G10

In contrast, the modern iteration of the G10 maintains its position as a steadfast symbol of excellence and a result of the innovation of thinner yet efficient and accurate movements.

The G10 of today was first established in the year 1987 when the watches started housing the thinner ETA 955 movements. The position of the battery hatch also changed slightly.

After the cessation of Tritium paint production for watches, the G10 began to feature Super-Luminova markings (an alternative that does not diminish its glow over time), indicated by the L on the dial. The G10's sleek and refined design is accompanied by an acrylic shatter-resistant glass and 5 ATM water-resistance for everyday splash-proof, a battery hatch for ease of battery change when the time comes. Weighing merely 38 grams, this watch exudes both reliability and accuracy while being discreet and unobtrusive on the wrist. The G10 is still available to this day.

The Rebirth of the Fatboy-80

The 'Fatboy' made a triumphant return in 2021 as the CWC G10 Fatboy-80, meticulously recreated to capture the essence of its historical predecessor.

The watch stays true to its roots with a Swiss-made brass 3-jewel movement – the ETA F06, the modern-day equivalent to the original ESA 536 and ETA 955 movements.

The G10 Fatboy-80 also boasts the vintage Super-Luminova dial and hands, offering an authentic nod to its historical past where Tritium was used. Notably, this historical timepiece proudly displays the old CWC logo and circle T, used for just two years before giving way to the iconic oval logo in 1982. This remarkable re-issue includes a battery hatch in the same position, an acrylic domed glass for a touch of vintage elegance, and weighs 48 grams, mirroring the iconic design and dimensions of the original 'Fatboy', paying homage to its heritage 41 years later.

With painstaking attention to detail, every element of this reissue has been lovingly crafted in Switzerland, ensuring an exquisite and authentic experience. You can buy the G10 Fatboy-80 by clicking here.
