The worlds of Bvlgari and Vianney Halter collide in the new Octo Finissimo Dual Time

Collaborations are hardly new to Bvlgari’s famed Octo Finissimo. The collection has previously provided a canvas for creatives including Tadao Ando, Kazuyo Sejima, and Lee Ufan. For Geneva Watch Days 2026, however, Bvlgari has taken the idea somewhere it’s never gone before.

The Bvlgari Octo Finissimo Dual Time x Vianney Halter is the first Octo Finissimo collaboration with an independent watchmaker and, more significantly, the first in which a horologist has built his vision from the collection’s movement.

That horologist is Vianney Halter, whose highly individual creations often resemble mechanical artefacts transported from an imagined past or future.

Aviation, graphic novels, industrial machinery, and science fiction inspire his work, with multiple displays and three-dimensional constructions among his signatures.

For this project, Halter worked with Bvlgari product creation executive director Fabrizio Buonamassa Stigliani to create what the maison calls a “retrofuture” inspired by Jules Verne and precision engineering.

An Octo Finissimo through Vianney Halter’s eyes

Rather than disguising the Octo Finissimo, the collaboration reimagines it within its distinctive geometric architecture. The familiar angular case remains, but four separate opaline displays transform the dial.

Two indicate the hours and minutes and GMT, respectively, while the smaller displays show the date and day/night indication. Halter’s characteristic blue hands are joined by a red arrow-shaped seconds hand, bringing further colour to the otherwise restrained composition.  

The Octo Finissimo’s disciplined geometry provides an unexpectedly natural framework for the independent watchmaker’s fascination with individual displays and mechanical instrumentation. 

That visual complexity hides considerable engineering. The 40.5mm case alone comprises more than 50 components, and Bvlgari must address everything from the flatness of individual parts to integrated crown guards and the manufacture of the four opaline displays. 

The team even developed dedicated tools to produce some of the watch’s miniaturised components.

A new calibre for the Bvlgari x Vianney Halter collaboration

Inside is the BVF 200 manufacture automatic movement, measuring 5.49mm thick and equipped with a micro-rotor. Running at 3Hz, it offers hours, minutes, small seconds, GMT, date, and day/night functions, along with a 60-hour power reserve. 

Finishing includes vertical Cotes de Geneve across the movement, complemented by brushing and perlage, while the platinum micro-rotor is engraved with Vianney Halter’s signature, adding his mark to the mechanics. 

Despite the additional displays and functions, the Octo Finissimo Dual Time × Vianney Halter remains relatively slender at 9.70mm thick. Water resistance is 30m.

Bvlgari is producing the collaboration in two limited editions. Ref. 104356 pairs a sand-blasted titanium case with an integrated titanium bracelet and is limited to 30 pieces. The 15-piece Ref. 104355 is the more precious interpretation, combining a pink gold case with a brown alligator strap and a pink gold pin buckle.
