The Octo Finissimo Automatic in titanium or steel is Bulgari's best value proposition; secondary prices are stable and the record-thin movement gives the watch a genuine story beyond its looks.
The Octo Finissimo Automatic holds the world record for thinnest automatic watch: 5.15mm total case height, with the BVL 138 movement measuring just 2.23mm. Bvlgari built this in titanium at 40mm, which means it wears like a chip of cool metal on the wrist. No compromise on wearability was made to claim that record.
Bvlgari launched the Octo line in 2012, then began systematically setting world records with ultra-thin variants across manual wind, tourbillon, minute repeater, and perpetual calendar complications. The automatic version arrived in 2017 and set its own record at the time, proving the feat was not limited to manually wound movements. The BVL 138 rotor is integrated into the movement architecture rather than stacked on top, which is how Bvlgari achieved the total thickness.
Titanium was the only case material compatible with the weight targets the engineers set. The Finissimo family has since become the most credible ultra-thin program from any manufacture, with record after record verified by official bodies.
The case is titanium, which scratches readily and cannot be polished back to factory condition the way steel can. The 5.15mm total height means the crystal sits very close to the movement, and a sharp impact on the crystal can transfer directly to the fragile rotor or bridges. Service access requires a manufacture-trained technician familiar with the BVL 138; not every watchmaker will touch it, and those who do often decline.
The bracelet integration is tight, and link replacement or resizing outside an authorized center risks misalignment of the thin titanium components. Because the record-holder status attracts attention, fakes and franken pieces exist, so provenance documentation matters more than usual for pre-owned purchases.
New retail is approximately $14,000 to $16,000 depending on market and configuration. Pre-owned examples in good condition trade in the $9,000 to $12,000 range, with condition being the primary driver given how easily titanium picks up wear. The record-holder story sustains demand, and the automatic variant is the most practical entry into the Finissimo family, which keeps secondary market interest steady.
The BVL 138 is an in-house Bvlgari caliber built to extreme tolerances and should be serviced only at a Bvlgari service center or an authorized partner with documented experience on the Finissimo family. Bvlgari recommends a service interval of approximately five years. Given the movement's 2.23mm height, disassembly and reassembly require tools and fixtures specific to this caliber.

Total watch height is 5.15mm; any claimed ultra-thin Octo Finissimo measuring over 5.5mm is incorrect. Cal. BVL 138 at 2.23mm movement height.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Total case height measurement | Total watch height at or near 5.15mm consistent with ultra-thin specification | Height exceeds 5.5mm; not the ultra-thin variant; counterfeit or wrong reference |
| case | Octagonal case finishing transitions | Sharp transitions between brushed and polished surfaces on octagonal case facets | Rounded transitions; over-polished case |
| caseback | Cal. BVL 138 designation | Cal. BVL 138 in-house ultra-thin auto at 2.23mm movement height; designation on caseback | Wrong caliber; non-ultra-thin movement; movement swap |
