Patek Philippe Neptune
The Patek Philippe Neptune, like the predecessor Nautilus, is a steel watch with an integrated bracelet. But it differs dramatically from the Nautilus in every detail: It has a round case and bezel and the bracelet, although novel in construction, is attached to traditional lugs. The defining feature of the Neptune was the multi-link "fish scale" bracelet, many of which include alternating scored and polished links. A double deployant clasp features a logo flap over the seam.
Neptune references included the time-only Ref. 5080/5081, complicated Ref. 5085, and ladies Ref. 4880/4881. The flagship Ref. 5085 featured a display caseback showing Cal. 240/164 with moon phase/date subdial, power reserve indicator, and small seconds at 4:30.
