The quest for thinness has been one of the watchmaker’s goals for a long time. By introducing the Octo Finissimo Tourbillon, Bvlgari has reached a new milestone in the development of ultra-thin watches with a major complication: its 1.95-mm-thick movement makes this flying tourbillon simply the slimmest on the market – no others even come close – and the thinnest ever made. This house movement is thinner than a Swiss five-franc coin, and right from the start, its design had to incorporate several solutions to reduce the overall thickness. The starting point was the tourbillon cage, a decisive factor in the construction process. It is 1.95 mm thick, a fact that shaped the rest of the structure. Once incorporated into the plate, the cage determined the thickness of the entire movement. The overall architecture also includes two bridges, one for the minute wheel and the other for the gear train of the tourbillon cage, which rotates once a minute.When all is said and done, everything about the Finissimo Tourbillon calibre speaks of mechanical innovation. It has 249 components and its finishes are completely in keeping with its exceptional nature, down to the last detail: the plate and bridges are bevelled and decorated with Côtes de Genève, the gears are bevelled and circular satin-brushed, screw heads and slots are bevelled and the ends are polished. The calibre, which displays the hours and minutes on a black dial, is lacquered and polished with great simplicity, and fits within a platinum case 40 mm in diameter, which extends into a black alligator strap with a platinum buckle. Without exaggerating the achievement, the Octo Finissimo Tourbillon represents a big step forward in the ongoing quest for thin watch complications.
