Collection
B1.618
The TONNEAU collection explores a distinctive case architecture defined by curvature, balance, and mechanical integration. Its form follows the natural shape of the wrist, offering both comfort and structural efficiency.
Combining refined proportions with technical intent, the tonneau shape offers Bianchet a platform where performance and elegance coexist in equal measure.

Designed
to be worn
The TONNEAU collection is engineered for natural wearability, with a 1.2 mm curved case profile. Lightweight titanium and high-density, scratch-resistant carbon ensure balance and comfort all day long, and resistance to shocks up to 5,000 Gs provides confidence in daily wear.
Contemporary Form
Introduced in watchmaking as an alternative to the traditional round case, the tonneau shape has long allowed greater freedom in proportion and architecture.
