Hi Mark

Its always fun sharing ideas about watches that differ from the norm and in so doing we increase the knowledge base for ourselves and the community at large. Sometimes these are simple to unravel and at other times not, resulting in a "reserved judgement" until further evidence becomes available. In this regard it is amazing to think how small the numbers really are - only two in the case of this Jordanian Air Force Carrera have surfaced. When I do get this particular watch I will take some close up pictures and see if that reveals any further information.
