Christiaan van der Klaauw Astronomical Watches is proud to announce the first watches to leave the atelier under the leadership of Master Watchmaker, Technical Director and co-owner Pim Koeslag.Celebrating this special occasion are three new steel versions of the Christiaan van der Klaauw Ariadne. ‘Steel combines a sporty look with our classic designs, it’s robust and timeless.’ Koeslag invited Jochen Benzinger to beautifully engrave the rotor in each of the new watches.
