As fresh as when it was produced a quarter-century ago, this rare medium-size Nautilus, reference 3900 in stainless steel was produced in small numbers from the mid-1980s to the mid-1990s. Exceptionally, the watch has a Sigma dial – notice the tiny Greek letters printed at the dial's lower edge. This signifier of high-quality yellow gold markers is normally only found on 1970s watches, but infrequently some late-model Pateks have Sigma dials, the present one being such an example. The alluring champagne dial compliments the brushed and polished gold of the classic Gerald Genta-designed 'sports' case. Inside is the venerable E23SC movement, a slim quartz 2.5mm calibre still used in the Nautilus 7010 to this day. The watch has Patek Philippe service history, and is simply irreplaceable in this absolutely exceptional condition. WATCH COMES WITH 12 MONTHS WARRANTY NO QUESTIONS ASKED.
