New Pictures of Bulgari's Calibre 168
CALIBRE 168
New pictures of Bulgari's first in-house movement, CALIBRE 168, a mechanical self-winding base movement entirely designed, developed and produced in-house. It was launched at Baselworld 2010 and now powers watches in the Sotirio Bulgari Collection.
Calibre 168 has represented the culmination of a lengthy verticalization process that has led the brand throughout the past decade to progressively establish and build an integrated manufacturing division. In these new pictures, we can get a better view of the sophisticated finishing that includes Côtes de Genève motif and a circular-grained mainplate, highlighted by the exquisitely crafted bidirectional oscillating weight.
POWERFUL TORQUE
In addition to the powerful torque with which it is possesses, Calibre168– which powers the Sotirio Bulgari line–features an instant-jump central date indication. Its other main characteristics include optimal recharging of the mainspring energy supply thanks to its bidirectional oscillating weight and winding system. Calibre 168 is equipped with a disconnecting-gear device for the automatic-winding system during manual winding. It optimises winding of the barrel via the crown and thus avoids any risk of premature wear of the automatic-winding gear train.
The construction of Calibre 168 also had to meet a set of technical constraints with a
few to future developments. These include a cross-through balance bridge endowing the regulating organ with sufficient rigidity to guarantee rating stability, while the main plate and bridges are machined from nickel silver, a metal alloy typical of high-end mechanical movements and which is complex to work with yet ensures impressive overall sturdiness and rigidity of the movement structure.
