Oyster Waterproofing

A hermetically sealed case architecture, guaranteed waterproof to 100 metres — elegance engineered for the elements.

President Bracelet

Three semicircular links, assembled and polished by hand until the metal moves like fabric on the wrist.

Superlative Chronometer

Certified to −2/+2 seconds per day after casing — a standard twice as strict as the industry's own observatory tests.

Cyclops Date

A sapphire lens magnifying the date two and a half times — the complication that made legibility a signature.
