Bulgari Octo Finissimo Guide · Fine Watch Guide

The Octo Finissimo shows what Bulgari's manufacture can do when it goes thin. The octagonal case comes from the Octo of 2012, which carries the case language of the Gérald Genta designs Bulgari acquired around 2000. The Finissimo arrived in 2014 with a hand-wound small seconds watch and a flying tourbillon, and on an ultra-thin watch the movement and the case are effectively one object. That makes the movement the first thing an owner should understand.

From the Octo to a thinner line

Bulgari launched the modern Octo in 2012, with an octagonal case that took its shape from the Genta lineage. The Octo Finissimo followed in 2014 as the thin extension of that idea. The first pieces were 40 mm platinum watches with black lacquered dials and alligator straps, and their thinness is the point of the line rather than a side effect of it.

The two 2014 calibers set the tone. The hand-wound BVL 128 drove the small seconds model at about 2.23 mm thick, with a reserve of roughly 65 hours. The BVL 268 drove the flying tourbillon, and Bulgari's launch catalogue described it as the thinnest tourbillon movement in the world at the time, at 1.95 mm. The watch itself was about 5 mm thick, which is a different figure from the movement's thickness and worth keeping separate in your head.

The family has grown well beyond those first two pieces. Each new generation has been a different engineering job, which is why the reference matters more than the collection name. A 2014 hand-wound piece and a later automatic can look almost identical from across a room and still be built on different calibers.

Le Sentier and the caliber family

Le Sentier is the location of Bulgari's movement manufacture, where the complicated and base calibers are developed. The Finissimo movements come from that workshop. The BVL 138, introduced in the 2017 automatic, is a Le Sentier caliber with a platinum micro-rotor, about 2.23 mm thick and a stated reserve of 60 hours at 21,600 vibrations per hour. Those figures show how little room a watchmaker has inside a case that is only about 5 mm thick.

Bulgari's after-sales guidance gives basic maintenance every two to three years and complete service every four to five years. The warranty is 12 months on basic maintenance and 24 months on a complete service. High jewelry, vintage pieces, minute repeaters and grande sonnerie are assessed individually. Intake runs through a boutique, an authorized retailer or Bulgari Customer Service, so decide which route the watch will take before you ship it.

A thin movement has less margin for error than a standard automatic. The barrel, the mainspring and the balance all have less room, and a careless opening can bend a bridge or damage a gasket that is hard to replace. Any specialist who takes one on should be able to show the bench work before the case is closed, and should explain what has been replaced rather than only what has been cleaned.

Ask for the power reserve to be measured after the service and for the result to be recorded. A shortfall after an overhaul can point to a worn barrel, a tired mainspring or a balance that has been adjusted poorly, and the workshop should be able to say which.

Buying a pre-owned Finissimo

Identify the caliber from the reference before you look at anything else. A hand-wound small seconds from 2014 and a tourbillon from the same year are different movements from the 2017 automatic. A listing that gives an automatic reference but describes a tourbillon movement has made an error, or is hiding one. Ask for the reference and a clear photograph of the movement through the caseback.

The 2017 automatic came in a 40 mm sandblasted titanium case about 5.15 mm thick. Its reference 102713 carries a titanium bracelet. The platinum in the watch's description refers to the micro-rotor, not to the case, which surprises some buyers who see platinum in a titanium watch's listing. Check that the case, bracelet and reference all describe the same watch.

Because the case is thin, look at the dial and the edges for damage that a thicker watch would hide. The early lacquered dials can chip or scratch, and a case that has been refinished will show softened edges on the octagon. Ask for the papers, and ask the seller to confirm in writing that the dial and case are original.

Care, originality and what to keep

Treat the case as thin rather than delicate. Ultra-thin cases flex more under a hard knock than thick ones do, so keep the watch away from desk corners and have the gaskets checked at every service. Pressure testing belongs in any full service, and the result should be recorded.

Straps and bracelets change both the look and the value of the set. The 2014 pieces came with alligator straps, and a replacement strap should match the original width and end fit. If a bracelet has been swapped, keep the original and write down which links are original. A complete set with papers and a box is easier to sell and easier to insure.

Finish is the last concern. A sandblasted titanium case shows marks differently from a polished one, and a refinish can turn an original surface into a new one that collectors will notice. Ask the workshop to record any finishing work and to photograph the case before and after, so the next owner knows what the watch looked like before.

Common questions

When was the Octo Finissimo launched?

Bulgari introduced the Octo Finissimo in 2014, with a hand-wound small seconds watch and a flying tourbillon, both in 40 mm platinum cases.

What movement is in an Octo Finissimo?

It depends on the reference. The 2014 pieces used the hand-wound BVL 128 and BVL 268, and the 2017 automatic uses the BVL 138 with a platinum micro-rotor.

How often does an Octo Finissimo need servicing?

Bulgari's published guidance recommends basic maintenance every two to three years and a complete service every four to five years. Confirm the schedule with the workshop.
