Poetic Horology: The Czapek Promenade "L'Écume des Jours"

Inspired by Boris Vian's classic novel, the Czapek Promenade "L'Écume des Jours" is a breathtaking masterpiece of artistic watchmaking limited to just 18 pieces. Encased in a 38mm stainless steel silhouette, its mesmerizing dial is a miniature canvas crafted in collaboration with Donzé Cadrans and MD'ART, featuring layered blue enamel, a mother-of-pearl piano-key chapter ring, a jade leaf, and a meticulously hand-painted titanium water lily serving as the small seconds indicator. Powered by the in-house Calibre SXH5.1 automatic movement with a platinum micro-rotor, this rare timepiece seamlessly blends literary romance with exceptional Swiss mechanical artistry.
