The new Giga Tourbillon is an exceptional model that required an extremely accurate development by a very dedicated team. Franck Muller’s research and development department has once again shown extraordinary expertise and vision by carrying out such a remarkable technical achievement.
Due to the large tourbillon, much more power is required in the watch. Here, it is powered by four barrels. The barrels are first paired in series to double the operating reserve; they are then assembled parallel to one another so that the power of the movement is doubled. The barrels, with a diameter of 16 mm, are 4mm wider than the traditional ones resulting in the almost constant force needed to operate the Giga Tourbillon.
Another special feature is that this exceptional movement has been reversed, with the bridges placed on the dial side, the hour setting and winding section located at the base and the hour hand uniquely positioned on top of the minute hand.
In order to ensure a 9-day operating reserve, displayed at midday, (traditional winding by the crown), the Giga Tourbillon has been designed to feature four barrels, in comparison to traditional tourbillons which generally are powered by only one or two barrels.
As the name implies, the special feature of the Giga is the very large 20 mm diameter Tourbillon occupying half of the watch.
A skeleton version which combines aesthetics and rigidity reveals a highly technical mechanism with perfectly balanced style.
