The Octo Finissimo Ultra COSC sets a new bar in high-end mechanical watchmaking. Never before has a mechanical watch resistant to shocks and magnetic fields been made so slim – even thinner than a coin. An achievement that exemplifies Bvlgari’s daring streak and relentless drive to keep pushing boundaries, the benchmark now stands at 1.70 millimeters.
A new feat with pushed boundaries.
Consider the significance of a 1.70 mm thickness – a ninth world record that introduces a novel standard in watchmaking. This new Octo Finissimo Ultra is not only the thinnest mechanical watch ever produced: it is also the world’s thinnest COSC chronometer. This milestone reflects a rigorous process, underscored by a commitment to reevaluate, and transcend the conventions of traditional high watchmaking, propelling venerable craftsmanship into a contemporary context. The outcome is notable; the unparalleled design of watch becomes evident upon first glance, prompting reflection on the innovation behind its creation. How is this even possible?
The journey to this record was formidable, beginning with the task of reconciling extreme slimness with robustness. Creating the world’s thinnest mechanical watch isn’t possible by building solely on existing concepts. It requires a paradigm shift, starting anew from the ground up.
This is precisely what Bvlgari accomplished with the unveiling of the Octo Finissimo Ultra and its remarkable thickness of only 1.80 mm in 2022. Emboldened by this achievement and convinced the limits had not been reached, Bvlgari’s R&D department, in collaboration with Concepto (experts in complex mechanisms), decided to push the envelope further still. Like a sprinter achieving a new personal best, each fraction of improvement demanded exponential effort. Surpassing already historic achievements is a testament to the power of innovation, determination, and the ability to question established norms.
Antoine Pin, director of Bvlgari’s watchmaking division, reflects, “The Octo Finissimo is a vast playground of innovation and design – and a source of unprecedented challenges – for Bvlgari’s R&D department. This marks the ninth occasion our engineers, watchmakers, and designers have defied the laws of physics to offer complex timepieces of unparalleled slimness. These accomplishments go deeper than the watchmaking prowess they represent: they define our DNA. Bvlgari stands to innovate, to keep pushing the boundaries, and to master the art of the extraordinary – and to always surprise.”
The art of Mastery
Given that the limits of movement slimness had already been reached with the Octo Finissimo Ultra, achieving an even slimmer profile for the Octo Finissimo Ultra COSC involved a rework of the case by optimizing the sapphire crystal. Through patient, meticulous incremental steps, the engineers were able to shave off that critical tenth of a millimeter – and establish a new world record.
In terms of the overall structure, the case back serves as the mainplate, upon which the 170 components of the manually wound BVL180 manufacture caliber are assembled. These components are selected using 1/10-micron optical measuring systems, so as to be able to select the parts that are closest to the perfect dimension, in order to exceed the precision of production resources. This COSC-certified mechanical movement introduces another layer of complexity and marks a first for the Ultra line.
The challenge of ensuring adequate rigidity for a watch measuring 40 mm in diameter and just 1.70 mm thick was met by crafting case back/mainplate from particularly dense, hard and ultra-resistant tungsten carbide.
Moreover, to maximize the use of the watch’s surface area, the hour and minute dials, the large barrel – with a 50-hour power reserve – and the escapement cleverly play with the circular geometry of the bezel opening, adjusting it ever so slightly.
Two years ago, the Octo Finissimo Ultra, which is still available by special order, opened contemporary haute horlogerie to new connected worlds. The QR code on the ratchet has now been transformed into a miniaturized Datamatrix on the back, it provides all the data relating to the watch and invites you on a personal journey into the Bvlgari universe. With images and videos, it provides a better understanding of the quest for ultimate finesse, the special skills and ingenuity that went into the creation of the Octo Finissimo Ultra COSC.
An exceptional watch needs an exceptional case: with the case dedicated to the Octo Finissimo Ultra COSC, Bvlgari reinvents the experience of setting and winding its watch. If you don’t want to use traditional methods, you can place your watch in the dedicated case, equipped with a digital display. The desired time is then programmed, and the adjustment cycle launched at the touch of a button. In a matter of seconds, the watch is perfectly adjusted and wound with impeccable precision. It’s like having a watchmaker at home.
As a hallmark of its era, the Octo Finissimo Ultra COSC (104081), a new milestone in the history of watchmaking, is being introduced in limited series of 20 pieces.
“What makes us so proud of the Octo Finissimo Ultra COSC is not just that it represents a remarkable triumph over the constraints of physics, but the spirit and depth of mechanical ingenuity behind it that so perfectly encapsulate the ethos of our Maison,” concludes Jean-Christophe Babin, CEO of Bvlgari. “To break new ground, to think differently in seeking to achieve greater reliability, performance, and elegance, that is what propels us forward.”
