A Slightly larger diameter with new dial color. The Ladies Automatic Nautilus in steel with diamond-set bezel asserts its presence on the wrist with a slightly larger diameter (35.2 mm instead of 33.6 mm). Patek Philippe has also revised its range of dial colors, introducing blue opaline, silvery opaline or gray opaline, grading to black at the periphery. The steel bracelet comes with a fold-over clasp, endowed with a new adjustment system, providing the wearer with between 2 and 4 mm of extra bracelet length for increased comfort.
