Wearing my Pierce on RAF two piece NATO. Don't think it was military issue per se. Definitely marketed to soldiers though it seems.
Did this one come from MWRforum a little while back? If it's the one I'm thinking of that was am excellent price and I must have looked at the thread 50 times Great watch either way.
Yes, that’s the one. I actually saw the same watch a year back while doing a google search and then it showed up for sale. Below is the link for the same watch. http://www.watchesandart.com/vintage-1970s-cwc-chronograph-for-british-military/ Also found another from 1972 last week. Landed yesterday.
