The Ladies Automatic Nautilus in steel with a diamond-set bezel has been updated with a slightly larger diameter of 35.2mm instead of 33.6mm. Patek Philippe has also expanded its range of dial colors, now including blue opaline, silvery opaline, gray opaline, and a black gradation at the periphery. The steel bracelet features a fold-over clasp with a new adjustment system that provides between 2 and 4 mm of extra bracelet length for added comfort.

The watch is powered by a self-winding mechanical movement with a Caliber 324 S C, a date display in an aperture, and a sweep seconds hand. The gray opaline dial has gold applied hour markers and numerals with luminescent coating. The steel case is water-resistant to 60m and features a sapphire crystal case back. The diamond-set bezel is decorated with 56 diamonds weighing approximately 0.67 carats. The watch comes with a steel Nautilus fold-over clasp.
