Bulgari Carillon Tourbillon, Daniel Roth Collection

The Manufacture Bulgari unveils the new Carillon Tourbillon (Daniel Roth Collection), a three hammer Grande Sonnerie (grand strike) timepiece that also houses a tourbillon. This timepiece offers the rarest carillon function for striking watches: a striking mechanism playing at least three notes. The Bulgari Carillon Tourbillon uses three hammers – one of the most refined and therefore most uncommon configurations. The Bulgari watches have lavished infinite care on making them as slender as possible so as to ensure the most delicate and melodious of sounds.

The energy stored by the watch is distributed to this impressively sophisticated movement, built around a Tourbillon. The mechanical hand-wound Manufacture Calibre DR3300 comprises 327 parts artfully arranged around the large tourbillon carriage. The two horological complications – the tourbillon and the carillon featuring an exceptionally pleasing chime – are entirely complementary. It houses two barrels: One keeps the striking mechanism running and is automatically rewound when the latter is armed, while the other guarantees a minimum 75-hour power reserve.
The gongs of the Carillon Tourbillon are delicately fashioned in several successive stages. These entirely hand-crafted special-shaped gongs serve to achieve a perfect and absolutely identical sound quality. They are bent and shaped by hand before being fired again and hardened at a temperature of around 900 degrees. They are then carefully cleaned and polished before a second firing in the furnace at a slightly slower temperature. The artisans also pay close attention to the toothing of the driving levers in order to create the best striking chords for the minute-repeater thanks to the three carillon hammers.
The architecture of Calibre 3300, the cut-out of the bridges and the positioning of the various parts are designed to be original, contemporary and contrasting so as to reveal the finesse and beauty of the mechanism. Moreover, the decision to rework the overall design also targeted the watch functions. The dial is suspended from the inner bezel ring and topped by a faceted sapphire crystal that is extremely complex to machine and polish. It serves to enhance the resonance of the striking mechanism while also providing enhanced lateral visibility of the mechanism. The striking lever has also been reworked and repositioned to ensure an optimal grip. Finally, the case itself has been redesigned and slimmed down.

Alternating between polished steel parts – hammer, gongs, tourbillon carriage – and open-worked surfaces, the finely decorated main-plate and bridges are given an elegant NAC surface treatment, an alloy exclusively composed of noble metals: platinum, rhodium, ruthenium and indium.
This new version of the Carillon Tourbillon watch provides a fresh interpretation of this exceptional model, featuring a slimmer pink gold case and subtly reworked to deliver enhanced legibility, while maintaining the signature characteristics of its original design, notably including the minute-repeater slide on the left-hand side of the case.

More rigorously restrained than ever and graced with clean-cut, straight hour-markers, this highly contemporary new version sheds the complex ornamentation of its predecessor to achieve greater maturity, elegance and finesse. The facetted sapphire crystal globe ensures even more precise readings and avoids any glinting.
