Rolex has only ever produced two watches that feature a triple calendar complication. While reference 6062 has the Oyster screw down case back, 8171 is fitted with a snap on case back. Produced between 1949 and 1952, reference 8171 was usually cased in yellow gold and pink gold, hardly ever in steel.

This large stainless steel 'Padellone' example is fitted with yellow gold numeral markers and 'Precision' on the subsidiary seconds dial. The watch has been cherish over the years and worn on occasions, however, the case with only the lightest of polish as the Rolex Coronet and case numbers are still clearly visible on the case back with the naked eye. What is also intriguing about the present watch, is the four digit stamped underneath the case number, which reads 3821. We have been unable to determined what these four digits refer to, but it is the only steel version we can find with these four additional digits. The case is incredibly crisp and very sharp to touch. The angled date and day apertures demonstrate this dial is original, along with the sharp track where the moon phase aperture meets the rim of the subsidiary dial. The outer date ring, too, is correct and the printing is the same as one would expect on an original example. The dial has aged to a warm white color, giving the watch a very charismatic look that vintage Rolex collectors love. It is so rare to find such a charismatic example.
