Housed in a 40 mm stainless steel case measuring just 8.3 mm in height, the Nautilus 5711-1A-011 features a screw-down crown, sapphire-crystal case back, and water resistance to 120 metres. The distinctive Nautilus silhouette is completed by a steel bracelet secured with a Nautilus fold-over clasp.
The silvery-white dial is appointed with gold applied hour markers finished with a luminescent coating, alongside a date aperture and a center sweep seconds hand — a refined, legible layout that stays true to the original Nautilus design language.
Powering the watch is the self-winding mechanical Caliber 26-330 S C, visible through the sapphire case back. Reference 5711-1A-011 represents the steel Nautilus in its definitive form, combining sporting proportions with the movement finishing that Patek Philippe is known for.
