Christiaan van der Klaauw

For several years, Christiaan van der Klaauw Astronomical Watches has placed its trust in SwissKubik to accompany its creations. Each automatic watch from the Dutch Manufacture is delivered with a Masterbox winder, designed to ensure the precision and longevity of its astronomical movements.

A collaboration built on technical excellence, reliability, and a deep respect for watchmaking craftsmanship.

A Maison Guided by the Stars

Christiaan van der Klaauw Astronomical Watches is a one-of-a-kind watchmaking Manufacture.


Founded in the Netherlands, it has embraced a singular mission: to represent celestial movements through horological mechanics. Since the 1970s, the Maison has been creating timepieces capable of displaying solar cycles, moon phases, and even the position of the planets.

Each timepiece is a tribute to astronomy and horological tradition.

Their signature model, the Planetarium, houses the smallest mechanical planetarium ever created: six planets orbiting the sun, each following its true orbital period.

"The Best Swiss Watch Winders"

Christiaan van der Klaauw watches are automatic: they wind themselves through the motion of the wrist.

When worn, an internal rotor captures these micro-movements and recharges the mainspring.

But when the watch remains still for several days, the spring gradually unwinds, the power reserve runs out, and the watch stops.

For a timepiece featuring astronomical complications, this means recalibrating the calendar, moon phase, or planetarium functions - a meticulous and time-consuming task, sometimes requiring a watchmaker.

This is where the SwissKubik watch winder comes in.

The right motion, even at rest

As Pim Koeslag, Master Watchmaker and owner of CVDK, reminds us, a watch winder is not a gadget, but a maintenance tool.

It limits manual handling, reduces wear on the crown, and ensures that the watch remains in optimal running condition.

At SwissKubik, we call this care through movement.

A Shared Legacy: The Love of Time

Between Christiaan van der Klaauw and SwissKubik, this collaboration was born of mutual respect—for time, for detail, and for precision.


Each astronomical watch delivered with a Masterbox winder symbolizes this alliance between two complementary forms of expertise: one reads the stars, the other safeguards the beating heart that brings them to life.


We warmly thank Christiaan van der Klaauw Astronomical Watches for their continued trust over the years.
It is a true privilege to support their creations and, in our own way, to help preserve the magic of movement.

Founded on Mutual Trust

For many years, Christiaan van der Klaauw has equipped its timepieces with SwissKubik Masterbox watch winders.

This trust is no coincidence, it reflects a master watchmaker’s conviction that a watch winder is not just an accessory, but a care tool, a natural extension of horological craftsmanship.

For SwissKubik, it is both an honor and a source of pride to support such a prestigious Maison.

Our two worlds share the same philosophy: preserving time, protecting mechanics, and honoring artisanal expertise.

SwissKubik – The Silent Guardian of Astronomical Precision

  • Engineered to faithfully replicate the natural motion of the wrist, the Masterbox ensures smooth, stress-free winding. Its pre-programmed cycles include carefully timed rest periods to preserve mainspring longevity and maintain movement precision, even when the watch is not being worn.

  • Beneath its minimalist design, the Masterbox houses a motor of absolute discretion.
    Designed and assembled in Switzerland, it delivers silent, consistent performance, an invisible yet essential technology that upholds the horological tradition it serves.

  • Magnetic fields are one of the invisible enemies of mechanical watches.
    Thanks to a rigorously shielded internal design, every Masterbox protects the movement from magnetic interference, preserving the accuracy of the calibre and the long-term reliability of your timepiece.
