I recently bought an Omega 30T2 the case #2292 - rear back inscription -Broad arrow and GB/159 - A29463, the main body is some form of alloy, the Bezel and case back is steel. The movement serial is 10222760. have taken a good many watches apart and I am almost a 100% certain the case has never been opened before. The puzzeling thing is the face the makers are inscibed on the back as being "Lemrich Swiss" it is silver with Gold arrow markers and 12-3-6-9 are raised gold, nothing like any RAF navigators watch face I have ever seen. I did hit a site which had a identical watch issued to NATO service members but unfortunately I did not Bookmark it and now cannot find it again. Can anyone kindly shed some light on this timepiece - Thanks Brian
