This exceptionally rare variant was only recently authenticated by Jack Heuer, although it was never officially offered for sale, we now think some were sold to the German/Swiss market. Estimates of numbers produced seem to range between 100-200, however what we do know is that less than 30 are currently known to have survived. It seems to be Heuers trial for the PVD process, of which Heuer was an early adopter. Leftover stainless steel cases from the 74033B/G variants (engraved 740303) were taken and converted for use. Note that the original serials were also coated during the PVD process, and need a strong loupe, and strong lighting to read. As with all Monacos the original seals often melted so dials were often stained, especially around edges. altough he balck dial is best suited of all the Monacos to hide this issue. Everything about the "Dark Lord" is unusual and along with the Chronomatic variant it is the holy grail of Monaco collectors.
