One doesn’t need to be a watch enthusiast to recognize and admire the Nautilus. Being a very short-lived reference from 2006 to 2009, the reference 5800 was launched alongside other significant contemporary Nautilus models, such as the ref. 5711, 5980, and 5712, marking the return of the coveted mid-sized variant previously known as the ref. 3800.

This reference serves as a transitional model that harmoniously blends elements of the past and present. Encased in stainless steel, the ref. 5800 is a rare gem that retains the timeless aesthetic of a monobloc case with an integrated sapphire caseback.

The present model features a 38mm case, slightly larger than the original 3800, while maintaining its signature blued ribbed dial. Underneath, the firm’s in-house cal. 330 SC drives the movement, equipped with a straight-line lever escapement, a shock-absorbing mechanism, a flat balance spring with self-compensating features, a monometallic balance, and the brand’s classic gold rotor, ensuring both robustness and precise timekeeping.

This Nautilus ref. 5800 from 2006 has been serviced at Patek Philippe in December 2022 and has remained in excellent overall condition since. It includes the Extract from the Archives and the service invoice, making it an ideal opportunity for collectors seeking to acquire one of the most exotic stainless steel Nautilus models ever produced.
