EVOLUTION DELPHIS SUB ZERO LIMITED EDITION OF 50

The Evolution Delphis Sub Zero CH-1426.1-BKSI is a study in restraint, precision, and extreme clarity. Limited to just 50 pieces, this striking timepiece draws inspiration from frozen landscapes where light is sharp, movement is deliberate, and every detail matters. Sub Zero captures that environment in mechanical form, translating cold purity into a refined expression of modern watchmaking.

Its curved dial is meticulously hand guillochéd and finished in icy, silver-toned hues that reflect light with crisp intensity. The engraved surface adds depth and texture beneath the clean, minimalist palette, creating a dial that feels both technical and elegant. The Delphis display presents time through an unconventional yet intuitive layout, reinforcing Chronoswiss’s long-standing commitment to alternative mechanical indications.

Powering the Evolution Delphis Sub Zero is the Manufacture Calibre C.6004, a next generation automatic movement developed in collaboration with La Joux Perret and introduced in 2023. Finished with ruthenium plating, a tungsten rotor, and Côtes de Genève radiating from the centre in harmony with Chronoswiss’s signature ray guilloché, the movement delivers a 55 hour power reserve and ensures smooth, precise performance.

The case is crafted from Grade 5 titanium, offering exceptional strength, corrosion resistance, and lightweight comfort on the wrist. Traditional handcraft remains central to the Delphis Sub Zero, from centuries old guilloché techniques executed on straight line and rose engine machines to the careful finishing that defines its refined character. Crafted in Lucerne, the Evolution Delphis Sub Zero represents a cool, disciplined chapter in Chronoswiss design, created for collectors who value precision, purity, and contemporary mechanical watchmaking at its most focused.
