British Army WW2 “ATP” Service Watch

Thinning down my own collection.
This is an opportunity to own, what I believe the maker to be – a “Fontainemelon” ATP wristwatch, as issued to the British military during World War II before the advent of the “Dirty Dozen” Style.
It has the original- very clean - cream dial with Arabic numerals & small second hand. Replacement leather strap, a long time ago. The watch keeps good time and I’ve worn it on a number of occasions. It has not been serviced – and the price reflects this
The ATP watches were supplied by 17 different Swiss manufacturers I have owned this watch for over 25 years. Mechanical Winder
