In celebration of Cortina Watch's 50th anniversary, Franck Muller has released five pièce unique renditions of its groundbreaking Revolution 3 Skeleton model.
Franck Muller debuted the triple-axis Revolution 3 in 2004, when it was the very first timepiece to feature a tourbillon that rotated on three axes, countering the effects of gravity from all directions.
Developing and producing such a marvel requires an exponentially greater amount of engineering and precision than a regular tourbillon. The three tourbillon carriages – one for each rotational axis – must be positioned relative to one another, and any irregularity will affect the entire system. A tri-axial tourbillon also entails additional mass that must be driven by the main spring, which in turn affects the movement’s isochronism and power reserve.
In the Vanguard Revolution 3, the three tourbillon carriages rotate at intervals of one, eight, and 60 minutes respectively, while two retrograde indicators flanking the tourbillon track the progress of the one-minute and eight-minute tourbillon carriages. It also offers an impressive 10-day power reserve.
