Explore Collection

Crafted Without Compromise

Every component earns its place.

Perpetual Movement

Calibre 3255 winds itself from the motion of your wrist, a self-perpetuating heart that never asks to be wound.

Everose Gold

Cast in an in-house foundry, the exclusive 18 ct pink gold alloy holds its warm blush for a lifetime and beyond.

Oyster Waterproofing

A hermetically sealed case, screw-down crown and fluted caseback guarantee integrity to a depth of 100 metres.

President Bracelet

Three-piece semi-circular links, reserved for this watch alone, close with a concealed Crownclasp of polished gold.

Superlative Chronometer

Certified twice over, then tested again after casing to a tolerance of −2/+2 seconds per day — twice the official standard.

Cyclops Date

A sapphire lens magnifies the date two and a half times, an emblem of legibility invented for this house in 1953.
