November 2012


Encased in this 45mm diameter DLC-treated titanium container is a mechanical movement that operates at 21,600 vibrations per hour and features two tourbillon cages weighing just 0.80 grammes. The inner cage, housing the balance wheel, balance spring and escapement, makes one complete revolution in 45 seconds, while the outer cage, rotating around a different axis, completes one revolution every one minute and 15 seconds. The entire assembly therefore makes one complete gravity-correcting revolution in 3 minutes and 45 seconds. Two co-axial barrels give the movement at least 72 hours of power reserve. Limited edition of 8 pieces.
