Hublot presents “LaFerrari” with a limited edition of 50 watches. A tribute to the Italian sports carmaker, the timepiece has achieved a historic record with its 50-day power reserve (produced by 11 mainspring barrels). This special series has no fewer than 637 components for movement and is equipped with a tourbillon complication.The face is made from sapphire crystal, shaped to commemorate the car’s design. The open case-back is made from PVD titanium. The time-setting crown and winding crown are completely integrated into the design and therefore practically invisible.
