Bulgari launches the Octo Finissimo Perpetual Calendar, extending its string of record-breaking ultra-thin watch debuts to seven since 2014. With a micro-rotor powering the watchmaker’s 2.75mm thin Caliber BVL 305, the new watch displays the time of day plus most the traditional perpetual calendar functions in a decidedly un-traditional ultra-thin 5.80mm-thick case.
The new perpetual calendar debuted last week during Watches and Wonders 2021 alongside other Bulgari collection updates. These include a new Serpenti high-jewelry model, four new gem-encrusted Divissima and Astrale cocktail watches and a special Octo Finissimo limited edition timer-only model designed by Japanese artist Tadao Ando.
We’ll detail these watches in upcoming posts. Below, let’s take a closer look at the Octo Finissimo Perpetual Calendar.
Retrograde displays
It’s not just the size of the Octo Finissimo Perpetual Calendar case that underscores Bulgari’s technical acumen. The watchmaker’s own history with retrograde displays, fueled in part by years of experience with this long-time Gerald Genta specialty (Bulgari purchased Gerald Genta in 2000), is front and center on the Octo Finissimo Perpetual Calendar.
The dial’s headliner is a retrograde date display, commanding the top and center of the dial, while a retrograde-display leap years indicator sits patiently at 6 o’clock. Radial, hand-indicated day and month displays fill the remainder of the octagon-framed dial.
And if this dial seems a bit spare for a perpetual calendar, that’s because there’s no moonphase display. Bulgari deems the lunar subdial, frequently found on traditional perpetual calendars, as too classical to contribute to the contemporary style of the Octo Finissimo collection.
The watch’s displays are adjusted by means of three correctors: one for the date at 2 pm, another for the month at 4 pm and a third for the day between 8 and 9 o’clock.
Bulgari notes that it met the challenge of devising a perpetual calendar within a slender case by effectively reassessing how a movement is configured spatially.
Previous Octo Finissimo models, such as the Chronograph GMT Automatic (2019) and the Tourbillon Automatic (2018), employ a peripheral rotor to free space within the movement. However, here Bulgari opted to re-format most of the perpetual calendar’s 408 components on one level around an efficient new micro-rotor. This freed enough space to allow Bulgari to retain many components at full size – and optimal efficiency – despite the caliber’s 2.75mm limiting thinness.
Two cases
Bulgari will debut the new perpetual calendar with the same architecturally stepped 40mm sandblasted titanium case we’ve seen on previous record-breaking ultra-thin Octo Finissimo models, consistent with the collection’s modern style.
Bulgari is also simultaneously creating a platinum-cased, blue-dialed example. However, this models’ platinum case (a first for this collection) is not fully polished, as is often the case with the luxurious metal. Bulgari will finish this premiere piece with a clearly contemporary satin brushing mixed with polished accents.
Prices: $59,000 (titanium case, titanium bracelet) and $89,000 (platinum case, alligator strap).
