Bvlgari Octo Finissimo returned to center stage at Watches and Wonders 2026 when Bvlgari unveiled a key update that reduces the case from 40 mm to 37 mm (about 1.46 inches), a change the brand says improves balance and wearability.
The new 37 mm Octo Finissimo keeps the collection’s signature octagonal geometry while tightening proportions to sit more comfortably on a wider range of wrists, Bvlgari said. The resize is paired with a new automatic movement and refinements across finishing and materials.
Bvlgari Octo Finissimo size change and design intent
Bvlgari engineers said the move to 37 mm was about proportional harmony, not pure downsizing. The 37 mm case preserves the Octo Finissimo profile while making the design feel more streamlined on smaller wrists, the brand added.
At the same time, Bvlgari retained the collection’s flat silhouette and stepped lugs, so the visual language remains unmistakably Octo Finissimo even at the new scale. Bvlgari presented the change at its Watches and Wonders 2026 display, where the new models sat alongside high-jewelry Serpenti Aeterna pieces.
Four initial 37 mm references and finishes
Bvlgari launched four 37 mm references. Model 104089 continues the collection’s industrial tone with a sandblasted titanium case and integrated bracelet, a monochrome dial, and black hands and hour markers, the company said.
Model 104351 shifts the finish, using a satin-brushed treatment on the case and bracelet and rhodium-plated hands and markers for a subtler, more refined look. Bvlgari described the two titanium versions as the everyday anchors of the new rollout.
The third reference is an all-gold version, crafted entirely in gold with a satin finish and a dial in the same metal. Compared with the titanium pieces, Bvlgari said the gold option emphasizes the material’s presence and gives the collection a contrasting, dressier expression.
New BVF 100 automatic movement and comfort gains
To accompany the 37 mm case, Bvlgari introduced the new BVF 100 automatic caliber. The brand said the movement has a 31 mm diameter (about 1.22 inches), a thickness of 2.35 mm (about 0.09 inches), and a volumetric reduction near 20 percent versus the previous generation.
Bvlgari described technical updates that include a redesigned bridge architecture and finishing, plus a platinum micro-rotor to improve winding efficiency. Power reserve is roughly 70 to 72 hours, a standout figure for an ultra-thin automatic, the company said.
The finished 37 mm Octo Finissimo weighs about 65 grams, or roughly 2.3 ounces, which Bvlgari says improves daily comfort. The brand pointed to the lighter titanium options as particularly suited to long wear.
Ultra Tourbillon in platinum, limited to 10 pieces
Bvlgari also extended its ultra-thin exploration with the Octo Finissimo Ultra Tourbillon in platinum. The case measures just 1.85 mm thick (about 0.07 inches) and is produced in platinum, a metal Bvlgari said presents major machining challenges at that scale.
The Octo Finissimo Ultra Tourbillon houses the hand-wound BVF 900 caliber, which Bvlgari lists with a 42-hour power reserve and a 4 Hz beat rate. The bridges receive a blue treatment to create additional visual depth, and the model is limited to 10 pieces, the company confirmed.
Serpenti Aeterna jewelry watches and gem settings
Alongside the Octo Finissimo updates, Bvlgari showed two new Serpenti Aeterna jewelry watches. One is a gold piece with diamond accents on the head and tail of the serpent, executed in a relatively restrained way, the brand said.
The other Serpenti Aeterna is a rose-gold model heavily set with approximately 493 gems, including 122 colored stones that span red tourmaline, amethyst, topaz, and emerald. Bvlgari said the two models use quartz movements, with the emphasis on form and gem-setting craftsmanship.
Bvlgari positioned the 37 mm Octo Finissimo rollout as a measured evolution, one that broadens the collection’s appeal while preserving its architectural identity. Watches and Wonders attendees responded to the mix of technical refinement and high-jewelry spectacle, the brand said.
Pricing and global availability for the 37 mm Octo Finissimo references will be announced by Bvlgari ahead of market launch, the company said. Watches and Wonders 2026 provided the first public viewing of the new pieces.
