The all-black appearance of Franck Muller’s new Giga Tourbillon watch unveils the daring innovations within. The extra large tourbillon is powered by four barrels, which are paired and then assembled in parallel to provide an impressive 10-day power reserve. You will also notice that the bridges are brought to the face of the dial, and the hour setting and winding section are moved to the bottom. All this is housed within the iconic Cintrée Curvex case in 18-carat white gold. Black PVD treatment gives this innovative watch a mysterious look.
