Patek Philippe Nautilus 5610/1P-001 '50th Anniversary' Platinum Blue Dial (2026)

The 5610/1P-001 is the most materially elevated of Patek Philippe's three 2026 wristwatch anniversary Nautilus editions — a 2,000-piece limited edition in platinum that reduces the case diameter from 41mm to 38mm, a decision with significant implications for how the watch wears and reads. At 38mm in platinum with the integrated three-link bracelet, the 5610/1P-001 occupies a size register that historically has been assigned to Ladies' and transitional Nautilus references, and the result is a watch that carries the full visual authority of the Nautilus design language with a discretion the larger editions cannot achieve. The platinum case introduces a distinctly cooler and denser wrist presence than white gold — the metal's greater specific gravity is perceptible on the wrist, and its characteristic grey tone reads differently against the sunburst blue dial than either white gold would. A single diamond set at nine o'clock marks the reference's status quietly.

The 38mm two-part platinum case carries contrasting polished and satin finishes, a diamond set at nine o'clock, a screw-down crown, and a sapphire crystal case back. The sunburst blue horizontally embossed dial presents white gold applied baton-style hour markers and white gold rounded baton hands, both with luminescent coating. The integrated platinum bracelet with patented fold-over clasp and lockable adjustment system completes the reference. Caliber 240, ultra-thin self-winding with anniversary-engraved 22K gold minirotor, powers the movement.
