The Bulgari Octo Finissimo | family history
Bulgari holds more world's-thinnest records than any other watchmaker, and all of them belong to the Octo Finissimo. The BVL 138 automatic movement measures 3.95mm thick. The tourbillon version measures 1.95mm. These are not marketing claims built on technicalities. They are verified by official bodies and they represent genuine feats of movement architecture that required years of in-house engineering. The Finissimo is also a beautiful watch: the octagonal case in titanium carries its geometry with a restraint that the original Roma does not attempt.
Bulgari's world-record ultra-thin collection: the Octo Finissimo Automatic (2017, cal. BVL 138, 2.23 mm movement, 5.15 mm case) held the record for thinnest automatic watch for several years. The Octo Finissimo design takes the octagonal Roman architecture of the Octo Roma and flattens it into a disc: titanium sandblasted case, integrated bracelet in a matching grain, sapphire crystal flush to the case rim. Each new Finissimo variant sets a fresh thickness record (tourbillon, chronograph, perpetual calendar) using Bulgari's in-house calibers engineered by former AP and IWC movement designers.
2014 · Launch and first ultra-thin record
Bulgari introduced the Octo Finissimo with the BVL 138 automatic, claiming the record for thinnest automatic watch at 5.15mm total case thickness. The record broke the Piaget Altiplano's previous mark. The titanium case was chosen specifically because titanium's strength-to-weight ratio allowed case walls thin enough to achieve the record while maintaining structural integrity.
2017 · Chronograph addition and further records
The Octo Finissimo Chronograph launched and promptly claimed another world record: thinnest mechanical chronograph at 6.9mm total case thickness. The movement architecture required designing a column-wheel and lateral clutch that could function within an extremely constrained vertical space. The chronograph variant demonstrated that the Finissimo platform could extend to complications without sacrificing its core ultra-thin premise.
2018 · Tourbillon and titanium exploration
The Octo Finissimo Tourbillon arrived at 1.95mm movement height, the thinnest tourbillon ever produced. Bulgari continued expanding the line with sandblasted titanium, skeleton dials, and ceramic versions through the early 2020s. The case diameter stabilized at 40mm, which proved to be the right proportion for a watch this thin to wear with substance.

How to read this family
What to understand before buying an Octo Finissimo.
- Finissimo Automatic or the Chronograph? The Automatic is the thinner, purer expression of the ultra-thin concept. At roughly 5mm case thickness, it disappears under a shirt cuff in a way that most dress watches cannot. The Chronograph adds complication and is thicker, but still thinner than nearly any comparable chronograph on the market. Choose based on whether you need a timer or want the thinnest possible wrist profile.
- Is a record-chasing watch actually wearable? Yes. Ultra-thin watches developed a reputation for fragility in the 1970s when the technology was immature. The Finissimo uses titanium specifically to compensate for the reduced material cross-section in the case. Bulgari warranties these watches for normal wear. The caveat is that any ultra-thin watch is more vulnerable to lateral impact than a standard-thickness case, and wearing one daily requires awareness of that.
- How does Finissimo compare to Piaget Altiplano? These two brands have traded world records back and forth for a decade. The Piaget Altiplano 900P uses an integrated movement-case design that achieves its record through architectural fusion. The Bulgari approach keeps the movement and case as distinct components. Neither approach is superior in absolute terms. The Altiplano is a more traditional luxury dress watch brand. The Finissimo is a more fashion-forward expression with Italian design DNA.

Which ref to buy
The Octo Finissimo holds multiple world records for ultra-thin movements. The automatic (BVL 138) is 2.23mm thick -- the world's thinnest automatic movement. The chronograph variant holds the record for thinnest automatic chronograph. The Octo Finissimo is Bulgari's technical achievement watch and a legitimate entry in the horological record books.
- 1Open
Octo Finissimo Automatic -- 2.23mm movement, world record ultra-thin, the legitimate horological achievement in the Bulgari catalog.
- The case for it:
- The BVL 138 at 2.23mm is not a marketing claim -- it is the documented thinnest automatic movement in production. The titanium case at 5.15mm total thickness wears like nothing else. This is a watch that advances what is mechanically possible, not just what looks expensive.
- Consider instead if:
- Ultra-thin movements are delicate. Service requirements are specialized. The Octo Finissimo is not a watch you buy and forget -- it needs careful handling and a watchmaker experienced with ultra-thin calibers.
- 2Open
Octo Finissimo Chronograph -- world's thinnest automatic chronograph, an even more demanding technical achievement.
- The case for it:
- Fitting a column-wheel automatic chronograph into a 6.9mm total case thickness while maintaining wearability is a genuine engineering feat. The Finissimo Chrono holds the record for thinnest automatic chronograph movement.
- Consider instead if:
- The chronograph costs significantly more than the automatic. The extra complication compounds the fragility concern. The automatic is the purer expression of the Finissimo concept.
