Mechanical poetry under a starry dial.
This edition of the Chronomaster Valjoux 23 brings a celestial twist to a historic chronograph. Beneath the shimmering aventurine blue dial lies the legendary Valjoux 23 VZ movement — a hand-wound column-wheel chronograph produced from 1916 to 1974 and revered for its reliability, beauty, and mechanical sophistication.
The movement is more than a mechanism — it’s a piece of horological heritage. And in this edition, its vintage soul is matched with a strikingly modern aesthetic. The deep blue aventurine dial glows with Super-LumiNova, giving it the look of a starlit sky. A refined blue leather strap completes the ensemble.
Crafted using fully restored, new old-stock Valjoux 23 calibers, this timepiece feels like owning a pristine vintage watch — without the compromises of age.
Limited to 25 numbered pieces worldwide.
The rarest stars belong on your wrist.
The Aventurine Blue Chronomaster Valjoux 23 is not just a timepiece — it's a rare encounter between mechanical heritage and visual wonder. The dial is made of deep blue aventurine, a sparkling material that evokes a midnight sky, contrasting beautifully with the crisp white printing and luminous accents.
Inside, the soul of the watch is a fully restored Valjoux 23 VZ, a movement beloved by watchmakers and collectors alike for its column-wheel construction and historical importance. First introduced over a century ago, this caliber remains a benchmark for mechanical chronographs.
Matched with a blue calf leather strap this edition is a refined take on vintage design with an artistic twist. Only 25 pieces exist — and each is a one-of-a-kind experience in craftsmanship, rarity, and beauty.
