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

Patek Philippe Nautilus 5610/1P-001 '50th Anniversary' Platinum Blue Dial (2026) brings together a 38mm platinum case, a sunburst blue dial, and an automatic movement, and production is limited to 000 pieces.

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. 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 case measures 41mm.

Caliber 240, ultra-thin self-winding with anniversary-engraved 22K gold minirotor, powers the movement.

The sunburst blue horizontally embossed dial is arranged with white gold applied baton-style hour markers and white gold rounded baton hands, both with luminescent coating.

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 integrated platinum bracelet with patented fold-over clasp and lockable adjustment system completes the reference.

A single diamond set at nine o'clock marks the reference's status quietly. This 2026 example is presented in new condition and accompanied by its original box and original papers.
