Item code: 15410

In 1980, the M.O.D. released a tender specification for the first quartz watch issued to all branches of the British forces. While the 70s tonneau shape case was specified, the early Swiss quartz movements couldn't fit this case and so the G10 "Fat Boy" was born.

Now, modern Swiss movements and manufacturing bring you the "Lost Boy", the watch that should have been made but never was... until now!

The Defence Standard for the "Watch, Wrist, Electronic, General Service" was dated the 29th of February 1980, a leap year day. Forty years to the day, it is making its debut. The T20 designation refers to the Tonneau case released 2020.
Engraving is available for this watch, however we cannot accept returns of any items that have been personalised.

정말 잘만든 시계 다른 브랜드의 비슷한시계들보다 퀄리티좋다

해외구매시 관부가세 붙어서 비싼감이 있으나 아깝지않다
그리고 스프링바 홀이 외부에 마감이 덜되서 살짝 보이는데 차라리 뚫어 줬으면 좋겠다 어차피 빠지지도 않는스프링바인데 ㅎㅎ

Fantastic watch

I purchased a CWC ‘British Military G10’ [80034] and was very impressed, so much so that exactly a week later I bought this, a CWC ‘T20 General Service Watch’ [15410] which, in my humble opinion, is a much better watch all round!

Love the watch, disappointed with the delivery

Superb watch, reminds me of my time in “the Royal Green jackets’ no fault to your company, but the Royal Mail ignored my instructions to deliver to my local post office for collection, and delivered to my home. Again please with my watch. Sapphire to be next purchase when next in stock.
