I have listed a Colbert with a broad arrow on the back of the case.

Colbert 663 15 Jewel Military MENS Wristwatch Vintage Broad Arrow Balance Good

I have no idea if it's indeed a true Military watch. But I bought about 300 wristwatch a few days ago. From a watchmaker clockmaker. And this was in the bunch along with a lot of chronographs.

Comments welcome

The A.T.P. stands for Army, Temporary Pattern. That along with the overall style would make this most likely early to mid-1950s in vintage. It would have been offically issued to a soldier in the British Army back then.

The ATP's were used and deliverd before the W.W.W. watches, used and delivered in the early to mid 40's ...The watch that went to war

BTW...The watch you sold was a Cortèbert, which might have helped when you listed it
