Housed in a 35.2 mm steel case measuring 8.62 mm in height, the Nautilus 7118-1A-010 features a sapphire-crystal case back and water resistance to 60 metres. The silhouette is completed by a steel bracelet secured with a Nautilus fold-over clasp.
The silvery opaline dial is appointed with gold applied hour markers and numerals, each finished with a luminescent coating. A date aperture and sweep seconds hand round out the display, keeping the layout legible and purposeful.
Powering the watch is the self-winding mechanical Caliber 324 S C, visible through the sapphire case back — a movement well regarded for its reliability within Patek Philippe's sports-watch lineup.
