You have to actually see it to get the full picture of this resolutely outsized model. The Giga Tourbillon by Franck Muller features an amazing 20 mm-diameter tourbillon carriage and four wide barrels guaranteeing a 10-day power reserve. The inverted movement is openworked, thereby giving this giant an especially light, airy feel. The sense of astonishment persists with the Black Croco and its PVD treatment. Designed like an extension of the black crocodile leather strap, the dial and the large Curvex case have been machined to create the appearance of alligator scales.
