This is impartial watchmaker Christiaan van der Klaauw Astronomical Watches’ first in-house motion, and just like the watches, it’s not your typical Swiss caliber.

Improvement began in 2017, in line with the manufacture, which means it took 7 years to create, which even for a watch motion being constructed from scratch, is an extended lead time.

The result’s the caliber CVDK which beats at 3Hz, has a uni-directional computerized winding rotor, 30 jewels, and 60 hours of energy reserve when absolutely wound. All fairly commonplace specs, till you get to the ending of the elements.

On the coronary heart of this gorgeous timepiece lies a variable-inertia stability wheel, meticulously designed to reinforce accuracy and dependability. The brand new motion encompasses a free-sprung stability spring, with Star-shaped bridges meticulously round completed by hand. The remainder of the motion is adorned in a frosted star sample with rhodium plating, complemented by perlage with rhodium plating on the mainplate. The rotor, crafted within the form of the CVDK brand, is skeletonized and plated in rose gold a testomony to each kind and performance.

This motion will act as a base for all of the timepieces throughout the assortment.
