Piaget has always understood that the Andy Warhol watch occupies an unusual position in the landscape of fine watchmaking. It is simultaneously a historically grounded collector's piece and a canvas for the kind of material audacity that the Maison has practiced since the 1960s. At Watches and Wonders Geneva 2026, the Bronzite High Jewelry piece ref. G0A51237 takes that proposition to its logical extreme, adding not only a very distinctive stone dial but also a case bezel set with a row of baguette-cut diamonds, framing one of the more quietly unusual dial materials in recent memory.
Things to Know About the Watch
The case maintains the collection's signature 45 x 43 mm cushion form in 18K rose gold, but here the top part of the case is set with baguette-cut diamonds. This architectural decision transforms the watch's familiar silhouette into something considerably more declarative. The dial is bronzite, a dark silicate mineral with a submetallic sheen that reads somewhere between iron-grey and warm brown depending on the light.
Bronzite is a ferriferous variety of enstatite belonging to the pyroxene group of minerals. Bronzite owes its visual identity to a process called schillerization: partial alteration of the mineral produces fine films of iron oxide along the cleavage surfaces, creating a bronze-like submetallic luster that shifts directionally with the light—an effect that can border on chatoyancy, though warmer and earthier than any conventional luxury dial material.
The most significant deposits are located in Austria, Brazil, Madagascar, South Africa, and Sri Lanka, with most commercial material coming from Brazil; historically, important sources include the Fichtel Mountains in Germany and Kraubat near Leoben in Styria, Austria.
Its use as an ornamental stone in high-end contexts is considerably rarer than lapis lazuli or malachite, which makes its appearance on a Piaget dial genuinely uncommon. The color reads dark—a warm, deep brown-black with a distinctive metallic shimmer—and it is an uncommonly masculine stone choice against a diamond-set rose gold case. The strap is in brown alligator with a pin buckle also in 18K rose gold, anchoring the palette.
The Movement
The new Piaget Andy Warhol watch with bronzite dial ref. G0A51237 is powered by the automatic Manufacture calibre 501P1. This automatic movement with 23 jewels beats at a frequency of 28,800 vph and provides a power reserve of 40 hours when fully wound. The movement features circular Côtes de Genève, a circular-grained plate, beveled bridges, blued screws, and a slate-grey oscillating weight in Tungsten. The movement is protected by a solid case back.
On the Wrist & Price
This is the Andy Warhol collection at its most unreserved with a High Jewelry exercise that makes no concessions to understatement. The bronzite dial provides just enough visual restraint to keep the diamond-set case from tipping into excess. For the collector who finds the standard Andy Warhol references too subtle, this is the logical answer.
