The present example sets the collectability bar well further up than an already highly prized standard 5004, as it features an extremely special personalized dial. The overall design is the “alternative” style reserved by Patek Philippe to special request timepieces, characterized by the double railway scales, an outer one for the tachymeter and an inner one for the minute divisions. It is known to have been featured on an extremely scarce number of special order specimens of reference 5004 and 3970. The Clapton 5004, to make an example, is one of the few pieces known with such a dial, and well defines the kind of collectors Patek Philippe granted such extremely exclusive pieces to. This specimen is however made even more unusual and collectable by two additional details: the dial and hands are luminous, an extremely rare and appreciated trait with remarkable impact on legibility and aesthetics.

Most importantly, the dial bears the Monogram 'MOS' at 6 o’ clock. This watch thus classifies in the extremely restricted ranks of Patek Philippe pieces with nominal dials, a privilege reserved for the likes of J. B Champion and Henry Graves Jr. Such watches are arguably to be considered a category of Patek Philippe pieces in their own right - similarly to the Graves watches, for example - thus ensuring unfathomable appeal for the collector of rare Patek Philippe wristwatches.
