BALANCE OF OPPOSITES

Performance Meets Elegance

Bianchet produces tourbillon timepieces exclusively. Not as a complication added to a watch, but as the watch's founding reason for existence. Every calibre is an in-house flying tourbillon, conceived, developed, and assembled in La Chaux-de-Fonds. The tourbillon is not the feature. It is the philosophy.

Double Strap

A vulcanized natural rubber strap with a titanium deployant buckle offers an alternative, integrating seamlessly with the case's rubber seam. Both options feature a quick-release mechanism for effortless interchangeability.

FLYING TOURBILLON

Born to defy gravity, the tourbillon mechanism, invented by Abraham-Louis Breguet in 1795, is considered the most prestigious Haute Horlogerie complication.

Crafted entirely from Grade 5 Titanium, including the bridges of the tourbillon cage, the architecture of our in-house skeleton movements forms a durable, resilient, and non-magnetic structure.
