Flying Tourbillon Sport GMT

Bianchet's flying tourbillon in a sporty guise, with a second time zone and 5,000 G shock resistance

Model History

Presented in 2024 as an evolution of the B 1.618 collection, the Flying Tourbillon Sport GMT pushes to the extreme the sporty character already suggested by the Tourbillon B1.618 Openwork, adding for the first time in the Bianchet catalogue a GMT complication paired with the flying tourbillon. The model was born in the context of the brand's collaborations with the world of racing — including its partnership with Maserati MSG Racing in Formula E — a link reflected in its technical language and stated shock resistance.

The tonneau case, available in carbon composite or in a hybrid carbon-titanium version, houses a manual-wind movement with a flying tourbillon positioned at 6 o'clock and a 24-hour subdial with a rotating globe at 12 o'clock, which makes the second time zone immediately readable at a glance. A crown-function indicator at 8 o'clock rounds out a legibility designed for active use, consistent with the model's "sporty" positioning within a catalogue otherwise oriented toward classical high watchmaking.

The brand states a shock resistance of 5,000 G for this model, a figure that goes beyond the typical standards of traditional watchmaking and reflects Bianchet's ambition to offer a tourbillon designed for a more dynamic everyday use than its dress-watch models.

Fun Fact

The rotating globe set into the 24-hour subdial at 12 o'clock is not just an aesthetic flourish: it turns in sync with the second time zone indication, offering an immediate visual reference to the hemisphere the displayed time belongs to — an uncommon solution even among high-end GMT models.
