BULGARI enriches its iconic Sotirio Bulgari collection by adding a limited edition Tourbillon Perpetual Calendar Wristwatch crafted in Platinum. It houses an in-house developed Automatic Tourbillon featuring a Perpetual Calendar with double coaxial retrograde hands.
The Tourbillon device limits the influence of gravity on the precision of the watch by mounting the escapement and regulation organ in a revolving cage that makes revolution per minute, thus compensating for inaccuracies caused by the vertical position. The Perpetual Calendar automatically adjusts the date to the length of the current month and also adjusts to leap years.
The BVL 465 caliber is an exclusive Multi-complication, developed and published by Bulgari, which features a unique paring of complications: a see trough Tourbillon and a Perpetual Calendar function with double coaxial retrograde display. The design and development of this new Bulgari “haut de gamme “ caliber took 5 years and required the contribution of 14 different specializations.
Its production calls for the highest level of craftsmanship and precision from the Master Watchmakers who work for 3 months to execute the 8,370 delicate operations that go into the manufacturing, assembly, finishing, setting and control of the 465 components of this caliber.
Bulgari’s meticulous attention to detail is exemplified in the range of refined finishing given to each of the components, such as “perlage”, “traits tires”, hand chamfering, black gold and the vertical “dresse” of the personalized 18-ct gold rotor.
