I have to say Rudi, some of us aren't quite fully sold on the concept they do agree just yet. There are anomalies on the one you show as noted in the thread.
Even if it does turn out that there is a black dial crosshair SMDV the chances of finding one will be so vanishing small as to be insignificant. I am reminded of a line in Chickenhawk, the Robert Mason memoir about his time in Vietnam. It goes something like 'of the 33 kinds of snake in Vietnam, 31 are poisonous with those ratios you can afford to come to a preludial judgement: kill them all.'
In other words, treat all black dial Omega dress watches as suspicious until you achieve the nirvana of knowledge that means you can spot a good one. Most of us never get there. Life is just too short.
