EVOLUTION TOURBILLON UNDERWORLD LIMITED EDITION OF 15

The Evolution Tourbillon Underworld CH-3123-BKPU is a dark, uncompromising expression of high horology, where mechanical complexity meets an almost subterranean aesthetic. Conceived as a statement piece, Underworld draws its power from contrast, depth, and raw architectural presence. This is not a tourbillon designed to be polite or discreet, but one that embraces intensity, shadow, and controlled aggression in every detail.

At the heart of the watch is a flying tourbillon, positioned prominently to command attention and emphasise the constant motion at the core of mechanical timekeeping. The open architecture of the dial reveals layers of depth, allowing the eye to explore bridges, components, and negative space. Dark finishes and purple accents introduce tension and visual energy, reinforcing the Underworld identity while preserving clarity and balance.

The case is crafted to enhance both presence and wearability, framing the dial’s dramatic composition while offering strength and comfort on the wrist. Finishing details reflect Chronoswiss’s dedication to traditional craftsmanship, applied here in a modern, deliberately provocative context. Every surface, angle, and opening is purposeful, contributing to a watch that feels engineered rather than decorated.

Designed and finished in Lucerne, the Evolution Tourbillon Underworld represents Chronoswiss at its most daring. It is a timepiece for collectors who seek emotion, mechanical theatre, and uncompromising individuality. Underworld does not follow conventions of classic tourbillons, it challenges them, delivering a modern interpretation of one of watchmaking’s most revered complications with confidence and intensity.
