After launching the world’s thinnest tourbillon model in 2014, Bulgari continues exploring the theme of extreme slenderness in the Octo Finissimo Minute Repeater, which is the world’s thinnest striking watch.
The BVL Calibre 362 measures j ust 3.12mm thick and the overall case thickness amounts to only 6.85mm. The case, made of titanium, is not only appreciably light but the low-density metal also ensures the best possible sound diffusion. The hour-markers on the dial, also made from the same metal, feature an incised, cut-out design, as does the small seconds counter at 6 o’clock: the openings serve to amplify resonance inside the case and optimise the sound effect.
The circular-section gongs directly affixed to the case are individually fashioned and finished by hand. From preparing and shaping the steel parts, to defining the notes and the harmonics, many stages are involved in producing the completed gongs. The extreme miniaturisation of the 362 components housed within this extremely slim case is vividly illustrated in the centrifugal strike governor, featuring a total diameter of just 3.3mm including its two inertia-blocks. The pusher activating the striking mechanism, fitted with an “all or nothing” safety device, is positioned on the case middle at 9 o’clock. It is designed to guarantee continuous water resistance to 50m. This exceptional hand-wound movement delivers a 42-hour power reserve once fully wound.
Octo Finissimo Minute Repeater lays the foundations of a new approach to mechanics and classic complications. Limited to 50 pieces.
