The present example of Jumbo Nautilus is first and foremost distinguished by its impeccable condition of both case and dial, and also by the presence of the original Certificate alongside with the coveted cork box - a collectible in itself - making it an unmissable opportunity for the most demanding of collectors. Originally introduced more than 45 years ago in 1976, the Patek Philippe reference 3700 redefined the meaning of luxury with the use of stainless steel for high-end watches. Reportedly designed by Gerald Genta practicality overnight after taking inspiration from ship portholes, the Nautilus is constructed via a solid mono-block case with clamshell construction. The still alloy used for it (chrome-nichel-molybdenum steel) was specifically developed by the brand for the Nautilus.

The production of the model is segmented into two main series with early examples (until the early 1981/1982) bearing reference 37000-001 and made by casemaker Favre-Perret . Later models - such as the present piece - have cases made by Patek’s in-house casemaker Atelier Réunis and bear reference 3700-011. These pieces feature a narrower bracelet tapering to 16mm, instead of the 18mm found on ref. 3700/1.
Inside the case beats the calibre 28-255C, developed on a Jaeger-LeCoultre ébauche famed for its performances and thus employed by other notable makers for their sport’s watches, such as Audemars Piguet (they used it for cal.2120 for the Royal Oak) and Vacheron Constantin (cal. 1120). Lean and refined in its profile at only 3.15mm, it is regarded as one of the most legendary movements ever produced.
