Finding the perfect accessory to compliment your Ferrari LaFerrari was a difficult task — until now. Developed alongside the Ferrari teams and in parallel with the car, the Hublot Masterpiece MP-05 LaFerrari Watch ($TBA) is a feat of engineering worthy of the venerable race car company's flagship. It's main claim to fame is a 50-day power reserve — a world record for a hand-wound Tourbillon wristwatch, and made possible by a custom movement designed, developed, and produced in-house. It also features the most watchmaking components of any Hublot watch, including a complex shaped sapphire crystal based on the car's outline, an open case back, a black PVD titanium case, anodized black aluminum cylinders with SuperLuminova markings for the hours, minutes, seconds, and power reserve indicators, and reinforcing bars on either side of the cylinders that serve as subtle nods to Ferrari's signature red color. The watch arrives in a leather and carbon fiber presentation case, and is limited to just 50 examples, which means only 1 in 10 LaFerrari owners will get to enjoy owning both.
