fter exploring ultra-miniaturisation in the fields of the automatic movement as well as the minute repeater, chronograph and tourbillon, Bulgari presents Octo Finissimo Perpetual Calendar, the slimmest in the world.

Once again this development redefines the limits of contemporary fine watchmaking, a dynamic that began in 2014 and involved rewriting the heritage conventions of traditional watchmaking year after year based on modern codes. A successful exercise: Octo Finissimo has set a trend and reinvented high-flying contemporary watchmaking. Aesthetics are inseparable from functionality when it comes to reinterpreting a sophisticated classic horological complication in a resolutely contemporary manner.

The outcome? No less than 408 components interacting within the extremely limited space provided by the slender 5.80 mm case of the Octo Finissimo Perpetual Calendar.

The development of the 2.75 mm calibre required the movement design engineers of the Manufacture in Le Sentier to devise new solutions, such as the use of a micro-rotor and the optimal use of the space between the components without reducing their dimensions.

This development powers the hours and minutes hands along with all the perpetual calendar functions: retrograde-display date, day, month and retrograde-display leap years. They 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.

Two versions are available, in titanium or platinum. Their owner will be able to read the time without worrying about having to adjust the indications before February 2100, a leap year that will require the adjustment of the functions by... his or her descendants.
