Bvlgari’s march into the haute horlogerie hall of fame continues, with a new interpretation of the Octo Finissimo Perpetual Calendar in blue titanium.
As the saying goes, heavy is the head that wears the crown. In the case of Bvlgari and its position in the watch industry, it absolutely applies. Year after year, the brand has pushed the boundaries of traditional watchmaking by consistently shattering records.
World’s thinnest mechanical watch, thinnest automatic, thinnest tourbillon in its various forms; All of these records have been held by Bvlgari at one time or another. Over the years, as records do, they get broken, but some achievements are so complex that they still stand today.
Case in point: the Bvlgari Octo Finissimo Perpetual Calendar. For five years running, it has been the thinnest perpetual calendar watch in the world, built to a level of finesse other watch brands can only aspire to match.
While expansions of the model line have understandably been minimal, that hasn’t stopped Bvlgari from introducing new iterations, including versions in rose gold and carbon fibre. This year, they’ve added yet another rendition of the world-leading design, now finished in a blue PVD titanium case with a blue varnished dial.
Thin Blue Line
A machine this intricate doesn’t really need to reinvent the wheel. Unsurprisingly, the Bvlgari Octo Finissimo Perpetual Calendar Titanium Blue retains the same case dimensions as its predecessors. Sized at 40mm wide, the watch wears like the pauldron of a Roman soldier, taking up prominent real estate on the wrist. The square silhouette also makes it wear larger than its round counterparts.
While this combination might sound obtrusive, it’s hardly the case. Thanks to the titanium construction, the watch feels lightweight and unobtrusive on the wrist. The blue PVD finish is also a familiar sight, having previously appeared on the Octo Finissimo Laurent Grasso collaboration from late 2024.
Better yet, the world record-setting thickness of just 5.8mm will undoubtedly allay any concerns about bulkiness in the wearing experience. Paired with a colour-matched blue alligator strap, the watch should articulate far better than it would on a solid bracelet, further cementing its wearability. As you might expect, though, water resistance sits at just 30m, so please don’t take it swimming unless you enjoy paying sizeable maintenance bills.
Blue World
In keeping with the monolithic nature of the case profile, the dial layout has been equally well thought out. Usually, perpetual calendar complications are small and difficult to read due to the sheer complexity of the mechanics involved, but Bvlgari has done well to ensure everything remains aesthetically consistent and highly legible.
Most distinctive here is the date indicator, occupying an inner arc that travels between nine and three o’clock. It’s brought together by a retrograde complication, meaning the blued pointer doesn’t need to complete a full revolution to display the date, but instead springs back into position. It saves a considerable amount of space on the dial, allowing the day and month sub-dials below to maintain their legibility.
Another retrograde mechanism sits at the very bottom of the dial, the leap year indicator, but as the name suggests, it only advances once every four years. Complemented by skeletonised dauphine hands, slim indexes and a blue varnished backdrop, the watch enhances its elaborate complications while also making them more intuitive for the everyday wearer.
Majestic Movement
And speaking of everyday, yes, this is a watch that can genuinely be worn every day. The reason lies largely in what can be seen through the open caseback. Inside sits Bvlgari’s Calibre BVL 305, which at the time of writing is still the thinnest perpetual calendar movement ever made.
Accounting for just 2.75mm of the watch’s 5.8mm overall thickness, the BVL 305 powers the perpetual calendar complication, both retrograde displays and a micro-rotor automatic winding system. Despite its incredibly compact dimensions, the Calibre BVL 305 still delivers the luxury-standard 4Hz (28,800VpH) beat rate alongside a respectable 60-hour power reserve. Combined with the automatic winding, the Octo Finissimo Perpetual Calendar becomes not only an everyday dress piece, but also one that can move in and out of a collection without the owner having to worry about fiddly adjustments.
Initial Thoughts
Heavy is the head that wears the crown, but Bvlgari perhaps wears it better than most. Having accumulated several crowns throughout its tenure, the Italo-Swiss brand’s latest release feels like something of a haute horlogerie victory lap. The Octo Finissimo Perpetual Calendar in Titanium Blue may not have changed the winning formula too much, but that’s why they call it a winning formula.
In my opinion, the blue-on-white contrast of the new model is both more serene than the industrial grey standard and less flamboyant than the rose gold rendition. It strikes an often-forgotten balance between complexity and simplicity, the truest form of elegance in luxury product design.
All in all, Bvlgari’s Octo Finissimo Perpetual Calendar still reigns supreme, and the new Titanium Blue model does an excellent job of making the world’s thinnest perpetual calendar feel just a little more humble than its title would suggest.
