The Patek Philippe Nautilus 4700/51 represents the Ladies' Nautilus in its original two-tone configuration — a reference that brings Gerald Genta's 1976 porthole design to a smaller case with the added material warmth of yellow gold details against the stainless steel body. Produced from the mid-1980s through the 1990s before the current 7118 and 7010 generations succeeded it, the 4700/51 occupies a specific moment in the Nautilus's evolution when quartz movements were considered the appropriate technology for a ladies' sports-luxury watch of this scale, and when the two-tone steel and yellow gold combination was at peak desirability across the entire industry. Today the reference attracts collector attention both for its historical position within Nautilus production history and for the elegance with which the yellow gold bezel and bracelet centres integrate with the champagne dial's warm tonal register.

The 27mm stainless steel Nautilus case carries a yellow gold bezel, with the characteristic porthole-form octagonal profile and integrated ear lugs. The champagne dial presents the Nautilus's signature horizontal embossed relief pattern, gold baton hour markers, and a date aperture at three o'clock. Gold leaf hands complete the dial. The integrated stainless steel bracelet features polished yellow gold centre links flowing from the case, with a fold-over clasp. A Swiss quartz movement powers the watch.
