Patek Philippe Nautilus Original

About this reference

The Patek Philippe Nautilus reference 3700/1A was produced from 1976 until approximately 1990. Collectors prioritize this reference as the original "Jumbo" model designed by Gérald Genta, featuring a two-part monobloc case construction with a water resistance rating of 120 meters. It utilizes the ultra-thin automatic Caliber 28-255 C, based on the Jaeger-LeCoultre 920 movement. Key technical details include the 40mm diameter, a date function without a central seconds hand, and a tritium-luminous horizontal grooved dial. Current secondary market valuations typically fall within the $120,000 to $180,000 range, though exceptional examples exceed these figures. A notable production variant is the "Albino" prototype with a white dial, while early "Series A" models are specifically sought after for their integrated bracelets featuring the "Gay Frères" maker's mark, distinguishing them from later production runs.
