Bianchet UltraFino Tonneau Full Ceramic: A Deep Dive into the New Blue and White Editions

Introduction

Bianchet, the independent watchmaker known for its avant-garde designs, has introduced ceramic versions of its UltraFino Tonneau. This model, first launched in 2025, marked several milestones for the brand: it was their first ultra-thin watch, first automatic movement, and first integrated bracelet design. Following iterations in titanium, sapphire, and carbon fiber, the new ceramic editions bring a classic material to the collection, available in deep blue and white.

Case and Design

The UltraFino Tonneau retains its signature tonneau (barrel) shape with dimensions of 40mm in width and 47.5mm in length. The case thickness remains impressively slim at just 8.9mm. The new ceramic cases are available in two striking colors: full white with dark blue gaskets, and deep blue with black gaskets. The finishing is consistent with previous metal versions, featuring vertically brushed surfaces and polished bevels. Water resistance is rated at 50 meters, and sapphire crystals protect both the front and back.

Movement and Dial

True to the model's identity, there is no traditional dial; instead, the movement is fully exposed on both sides. The Deep Blue edition features a black PVD treatment on the movement's bridges and plates, while the White edition uses a cobalt blue PVD for a more contrasting look. The flying tourbillon regulator is visible at 6 o'clock, adding to the visual appeal.

The in-house UT01 automatic caliber powers the watch. It is remarkably thin at 3.85mm and weighs only 8 grams, making it one of the lightest automatic tourbillons in production. Constructed entirely from titanium, the movement includes a suspended mainspring barrel and a one-minute tourbillon with a 2.66mm cage. It operates at a frequency of 21,600 vibrations per hour and offers a 60-hour power reserve. Despite its lightweight construction, the movement is engineered to withstand shocks up to 5,000 G.

Bracelet and Strap

The integrated bracelet is also crafted from ceramic, matching the case material and finish. It features satin-brushed surfaces and polished accents, and is equipped with a quick-release system. Additionally, each watch comes with a rubber strap—black for the Deep Blue edition and cobalt blue for the White edition—included in the presentation box.

Pricing and Availability

The ceramic Bianchet UltraFino Tonneau is part of the permanent collection. Both editions are priced at CHF 72,500 (excluding taxes). For those interested in acquiring one, it is recommended to contact authorized retailers or visit the brand's official channels.

Buying Tips and Authenticity Notes

When considering a purchase of the UltraFino Tonneau, verify the authenticity by checking the unique serial number and the hallmark of the flying tourbillon. Given the high price point, it is crucial to buy from authorized dealers or reputable sources. The ceramic case is scratch-resistant but can be brittle, so handle with care. The included rubber strap offers versatility, but ensure the quick-release system functions properly.

For replica-watch enthusiasts, note that authentic Bianchet timepieces feature intricate movement finishing and specific engravings that are difficult to replicate. Always compare the weight and feel of the watch, as genuine ceramic has a distinct density. If in doubt, consult a certified watchmaker.
