Lot Essay
The present watch is a rare and lesser known variant of reference 8171 in yellow gold: whereas the vaste majority of all reference 8171 watches feature the Rolex crown above the calendar windows, the present watch stands out by having an inverted layout, the Rolex crown below the calendar windows and the "Perpetual" above them. One must assume that Rolex intended to emphasize the fact that this watch was a rare combination of full calendar and automatic winding, a formula which many other distinguished Geneva manufacturers did not introduce for nearly a decade.
Rolex has produced only two different models of moonphase wristwatches, references 8171 and 6062. Both models are automatic, however reference 8171 has a snap on back, while reference 6062, the Oyster version (see the previous lot), has a water-resistant-type screw back.
Reference 8171 is considered very rare as it was produced in a small series between 1949 and 1952. It was made in stainless steel (see lot 347 in this auction), 18K pink or yellow gold.
The model is illustrated in The Best of Time - Rolex Wristwatches by James M. Dowling & Jeffrey P. Hess, p. 209.
