The Bulgari Octo Finissimo (Ref. 103431) is an architectural masterstroke—where horology, Italian design, and technical finesse converge in an ultra-thin profile that defies expectation. Known for its radical geometry and award-winning slimness, this reference marks a significant evolution of the Finissimo line: a stainless steel case with a bold satin-polished finish that adds new depth and versatility to its already iconic form.

The case measures 40mm across, yet it’s the mere 6.4mm thickness that makes the real statement—flat, refined, and effortlessly elegant on the wrist. Composed of over a hundred facets, the Octo’s multi-layered case draws inspiration from Roman architecture and modernist design alike, combining round and square motifs in perfect tension.

The blue sunray dial adds a fresh vibrancy, with minimalist indices and offset small seconds at 7 o’clock giving it a restrained, almost meditative tone. Despite its artistic simplicity, the dial remains unmistakably bold—Bulgari’s answer to contemporary watchmaking’s quest for purity of form.

Beneath the surface lies the in-house BVL 138 Finissimo caliber, a micro-rotor-equipped automatic movement measuring just 2.23mm thick. It delivers a 60-hour power reserve and is beautifully finished with Geneva stripes, perlage, and polished bevels—all visible through the sapphire caseback.

Fitted with an integrated satin-polished steel bracelet that flows seamlessly from case to clasp, the 103431 wears like sculpture—fluid, cool to the touch, and remarkably comfortable.
