First Look: Christiaan van der Klaauw Goes Openworked with the new Planetarium Skeleton

Christiaan van der Klaauw has been making mechanical astronomical watches for the reason that Nineteen Nineties, and the Planetarium is the defining complication of the Dutch manufacture. The primary Planetarium wristwatch appeared in 1999 and featured what remains the world’s smallest mechanical planetarium. The complication has since been interpreted in quite a few methods, most not too long ago together with the Grand Planetarium Eccentric and the unique Planetarium Julie. The brand new Planetarium Skeleton Platinum makes use of the latter’s openworked design, making it a limited-edition mannequin.

The watch is offered in a 40mm platinum case, is 50m waterproof, and options sapphire crystals on each side. The case design is acquainted, with an onion crown and straight lugs. The clear sapphire dial adjustments the way in which the Planetarium is skilled, with a lot of the astronomical module’s mechanical construction seen. Blued Roman numerals span 9 to three, occupying solely the higher a part of the dial (“above the horizon”) and offering reference for studying the time. The open structure takes up a lot of the house.

At 6 o’clock, the Planetarium shows the orbits of six planets in actual time: Mercury, Venus, Earth, Mars, Jupiter and Saturn. The Solar is on the centre, with every planet following its personal exactly calculated path. Mercury completes its displayed orbit in 87.97 days, Venus in 224.70 days and Earth in 365.24 days. Mars takes 686.98 days, whereas Jupiter requires 11.86 years and Saturn 29.46 years. Date and month indications on the subdial at 12 o’clock full the astronomical show alongside central hours and minutes, all indicated by blued palms.

The construction surrounding the planets is one thing else. The customized bridges have been formed just like the Christiaan van der Klaauw emblem, itself representing the Solar with twelve radiating claws. On this skeletonised model, these varieties develop into useful components of the motion building, extending across the Planetarium module and exposing extra of the gearing beneath the sapphire dial. The bridges and plate are rhodium-plated for a constant metallic look in opposition to the clear dial.

As in the original 2000 Planetarium, on the blue planetary rings, the color begins vivid gentle blue across the Solar and progressively darkens in the direction of the outer orbits, representing the reducing depth of daylight as the space from the Solar will increase.

Behind the dial is the CKM-01 manufacture motion, an automated calibre developed for Christiaan van der Klaauw. It’s the similar base as utilized in the Grand Planetarium Eccentric, developed with the motion maker UhrTeil AG (based by Andreas Strehler). It makes use of a free-sprung hairspring and variable-inertia steadiness wheel, working at 21,600 vibrations/hour and offering 60 hours of energy reserve. The ending contains round ornament on the star-shaped bridges, frosted star ornament, perlage on the principle plate and rhodium plating. The skeletonised rose gold-plated rotor takes the type of the CVDK emblem and incorporates a rhodium-plated tungsten weight.

The Planetarium Skeleton Platinum is worn on an FKM sailcloth strap closed with a stainless-steel folding clasp bearing a platinum CVDK emblem. The watch is restricted to 6 individually numbered items and is priced at EUR 86,000 excluding VAT. For extra particulars, please go to www.klaauw.com.
