Stone dials emerged as one of the defining trends at Watches and Wonders 2026, bringing a sense of natural artistry to the forefront of watchmaking.
More than just a source of colour, materials such as sodalite, onyx, malachite, and green aventurine transformed dials into miniature landscapes of wearable geology. With their distinctive veining, textures, and patterns, no two stone dials are exactly alike, giving each timepiece a unique character while showcasing the beauty of nature through high horology.
Piaget’s Sixtie translates the maison’s longstanding fascination with ornamental stone dials into a more compact, sculptural form. First introduced last year, the trapezoidal design returns with a blue quartz stone dial, bringing natural variation and depth to an otherwise minimal silhouette. The dial becomes the focal point: subtly irregular, inherently unrepeatable, and deliberately resistant to industrial uniformity, reaffirming Piaget’s belief in material as the primary design gesture.
Audemars Piguet pushed the idea further still, extending stone from the dial into the mechanics themselves. The Établisseurs Galets, part of the newly launched Atelier des Établisseurs collection, revives an old model of watchmaking built on specialist collaboration—separate hands for cases, dials, gem-setting, bracelet-making, and movement construction, each contributing a discipline the others don’t have. The watch takes its cues from the Lac de Joux, its stones tumbled and rounded into pebble forms as though shaped by decades underwater.
What sets it apart is what’s hidden: a movement engineered to mirror that same pebble outline, so the mechanical architecture echoes the stone rather than sitting inside it as an afterthought. AP is launching the line with a turquoise-and-tiger’s-eye pairing, with five more stone combinations arriving across the year.
Zenith took a more composite approach with the G.F.J. Bloodstone, a new 161-piece yellow gold edition of its Calibre 135 revival. Rather than letting stone take over the whole face, the dial is built in three distinct layers: a central disc in bloodstone, a mother-of-pearl small seconds counter at 6 o’clock, and a peripheral guilloché sector referencing the brick façade of Zenith’s Le Locle manufacture. It’s the bloodstone at the centre that does the trend’s real work: its natural veining and inclusions mean, as with every hardstone dial this year, that no two pieces come out the same.
Paired with a Calibre 135 rebuilt for modern chronometry (72 hours of power reserve, COSC certification, and a lineage tracing back to a record five consecutive first prizes at the Neuchâtel Observatory), it’s a reminder that this material isn’t only being used for its looks—brands are increasingly trusting stone to carry watches with serious mechanical credentials, not just decorative ones.
Seen together, these releases suggest hardstone has moved past being a seasonal dial finish. It’s becoming a starting point—something brands are now designing cases and movements around, rather than adding on at the end.
