Since its introduction in 1976, the Patek Philippe Nautilus is one of the key players who transformed the concept of a luxury sports watch in steel, revolutionizing the watch industry. Designed by the legendary Gérald Genta during a quick sketch, it evolved into a timeless horological masterpiece, now famously known as the "Jumbo" Nautilus ref. 3700. At the heart of this 42mm watch lies the caliber 28-255C, which draws its design from the Jaeger-LeCoultre caliber 920 introduced in 1967. The caliber with its lean profile at just 3.15mm, is regarded as one of the most legendary movements ever produced.

The production of the ref. 3700 was divided into two main series, with early examples (1976-1982) stamped as ref. 3700/1, while later examples (1982-1990) are marked as 3700/11. Early models featured a slightly wider bracelet measuring 16mm, whereas later iterations were tapered down to a sleek 14mm.

Extremely well-preserved, the present Jumbo featuring a full gold livery belongs to the later production series of the ref. 3700/11. Previously unknown, this stunning example showcases a case with desirable bevels and sharp hallmarks at the caseback, while the gold bracelet remains rigid and tight. Accompanied by a striking blue-black dial that is as well-preserved as the case, this watch is further authenticated by the Patek Philippe Extract from the Archives, confirming its date of manufacture in 1984. In excellent condition, this is a rare opportunity for any vintage Nautilus enthusiast to acquire a remarkable yellow gold example for their collection.
