The project took shape from the observation that the wristwatch is rather placed, for most of its time, in the horizontal position and the tourbillon mechanism produces its effect of compensating gravity when it’s in the vertical position. The collaboration and discussions with the designer Benjamin Müller led us to put the tourbillon on the vertical position and to place it in the centre of the dial. The feeling to work in the right direction was immediately reinforced by the first sketches, the balance and the elegance of the whole.

About the Klepcys Vertical Skeleton Tourbillon

For the first time in history, CYRUS has placed a tourbillon in the middle of the dial on a vertical axis in a wristwatch. By doing so, this breaks the age-old rule that finds the tourbillon normally on its horizontal axis at 6 o’clock on the dial. This break from tradition wasn’t done simply for aesthetics.

Studies by our team indicate that the 90° angle of the tourbillon better combats the effects of gravity on the movement over the course of normal daily wear. At this angle, the cage containing the entire regulating mechanism rotates on itself to offset the negative effects gravity has on the balance wheel more effectively. Ultimately, the vertical position has a great impact on the overall performance of the watch.

The 3-D architecture of the dial, also in a skeletonized version, is enhanced by the arch of the vertical bridge. Inspired by Leonardo Da Vinci’s design principles, the bridge blends harmoniously with the symmetrical lines of the timepiece and accentuates the central tourbillon. This provides easy access to admire the tourbillon as it completes a full rotation every minute.

The in-house manufactured manual-wind movement houses two barrels, offering a power reverse of more than 4 days.
