Cvstos Challenge III Tourbillon Differentielle watch
Cvstos, a brand dedicated to high complications and bold avant-garde designs, unveils the fruit of several years of research and development in the form of the Double Tourbillon Differentielle. The new timepiece, created in a limited edition of just 25 pieces, carries two patented innovations and is a world premiere.
Just 25 pieces of each Cvstos Challenge III Tourbillon Differentielle watch will be made.
The Double Tourbillon DIfferentielle is powered by the new hand-wound mechanical caliber CVS8850, that was developed in cooperation with Telos Watch. It offers two independent flying tourbillons, each beating at 4 Hz. One of the patents is for the innovative system where four barrels are connected in parallel on the main plate to ensure enough power supply to drive the two tourbillons. The arrangement ensures that all four barrels operate simultaneously and precisely averages out the rate of the two. The second patent is for the differential gear system, which is mounted on high-tech ceramic ball bearings instead of rubies to reduce friction, wear and tear.
The movement of the Cvstos Challenge III Tourbillon Differentielle watch is built on four levels.
To showcase this movement to its fullest, Cvstos houses it inside the Challenge III case and into its Sealiner case with nautical features. Both of these cases deliver sweeping views of the complex moment. Additionally, the three-dimensional dial is open worked. Essentially, the 364 movement components are arranged on four different levels, making for a dramatic depth and dimension. The Swiss-made watches boast 60 hours of power reserve when fully wound.
Each Cvstos Challenge III Tourbillon Differentielle watch will sell for approximately $205,000.
Depending on the version, the watches are crafted in 18-karat 5N rose gold, titanium or steel and feature different colorways that range from rich royal blue to bright orange and stealth black. As mentioned, just 25 pieces of each rendition will be made due to the time-consuming feat of building this highly complicated four-level movement. The watches retail for CHF 190,000 – or just about $205,000.
