STYLISH

TONNEAU CASE

Invented by Cartier in 1906, the tonneau case was conceived to be both elegant and comfortable. A very innovative shape at the time, it still represents the epitome of class and sophistication.

By reinterpreting this iconic watch case, adding pure lines and perfect proportions, underlined by refined colour details, Bianchet goes beyond comfort and elegance to create

 

a sporty elegant case

 that is artful in every detail.

The use of exclusive high-tech materials, such as Titanium-Dust-Infused-Carbon with its unique precious reflections, the perfect curves, the lightness and the softness sensation brought by the vulcanized rubber, create a unique horological experience.

CALIBRE
TOURBILLON
 

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

This complex mechanism requires a high level of expertise and precision to construct, and remains a symbol of

horological excellence

to this day.
