Congrats, that's one of my favorites. Now you'll have to research it to figure out if it's a birth-year watch. I know that "6BB" RAF versions have the year encoded into the case-back numbers, but I have no idea how to date the "0552" Navy chronographs.
Very nice watch. No way would my wife know where to start in choosing a watch for me despite all the hints ...
on Saturday afternoon we attended my friend daughters wedding and if anyone know a Scottish wedding theirs drink in abundance so I took the opportunity to ask how she managed to get a near perfect lemania ? her reply was simple I just looked through you watch hit list till I found one that wasn't scored out phoned a couple of your friend and presto that was it simple when you know how she said.
