The Bianchet Flying Tourbillon Sport GMT pairs a manually wound flying tourbillon with a two-time-zone display: central hands show local time, while a 24-hour subdial and rotating globe indicate reference time. Bianchet introduced the model in 2024; its current collection page lists carbon versions at CHF 75,500 and Hybrid Gold at CHF 95,500, both excluding taxes.
How does the Bianchet Sport GMT work?
The watch is designed to show two time zones at once. The central hands display local time. A separate 24-hour indicator displays reference time, with a globe that Bianchet says rotates alongside the hour hand. The 24-hour scale distinguishes day from night in the reference zone.
A crown-function indicator is intended to show whether the crown is being used to wind the movement, set local time or set reference time. Bianchet’s description establishes the intended functions, but does not provide independent testing of the mechanism.
Movement and specifications
Bianchet lists an in-house, manually wound movement with a 60-second flying tourbillon. The maker specifies Grade 5 titanium for the main plate, bridges and tourbillon cage. These are manufacturer specifications, not independently verified performance results.

| Variant | Case and weight | Official listed price | Strap and clasp details |
|---|---|---|---|
| Carbon versions | Titanium-Dust-High-Density-Carbon case. Carbon Fern Green is listed at 56 g without strap. | CHF 75,500, excluding taxes | Carbon Fern Green is supplied with natural-vulcanized-rubber straps and a Grade 5 titanium folding clasp. |

The Carbon Fern Green product page (reference CBFGFTSG4) describes two straps. Strap and clasp details in the table are specific to the named product pages; the collection listing does not establish that every variant has identical accessories. The official pages list a five-year guarantee.
The practical distinction is material and presentation: Carbon uses the carbon case construction, while Hybrid Gold adds solid yellow gold to the bezel, back and crown. The specified weight figures apply only to Carbon Fern Green and Hybrid Gold, both without straps. Current listed prices and availability may change, so confirm them with Bianchet before purchase.

What makes it a new model?
Monochrome Watches covered the Flying Tourbillon Sport GMT’s introduction on March 27, 2024, describing six debut references and reporting the initial CHF 75,500 excluding-tax price. Bianchet’s current collection page lists seven versions, including the Hybrid Gold, and is the relevant source for its current listed prices.
In a March 12, 2025 ambassador announcement, updated May 18, 2025, Bianchet attributed a statement about the brand and racing to Formula 1 driver Esteban Ocon. That is a brand-published ambassador quotation, not independent product testimony.
