The Signal Was Beautiful.
If aliens wanted to send a signal to the most glamorous wrists of Earth, this would be it.
The Piaget Opal Onyx is less of a watch and more of a cosmic communiqué—a radiant series of concentric circles that somehow landed perfectly on a wrist. Center stage is a slice of electric blue opal, swirling with greens and violets like some interstellar nebula trapped in stone. The color shifts with the light, never looking the same twice—think aurora borealis meets '80s disco. Encircling that is a tight row of diamonds, then a stealth ring of black onyx, and finally, a dazzling bezel of even bolder stones. Crop circles? Try crop ovals. Either way, they've made contact.
The case and bracelet are, of course, 18K yellow gold—this is Piaget, after all, the House of Gold™ (not officially, but it really should be). Circa 1980s, this model captures that golden-era Piaget mood when opulence was the assignment and they really didn’t leave any gemstone unturned. Couldn't decide between opal, diamonds, onyx, or gold? Use all four. Problem solved.
At 31.5mm, it’s a midsize that manages to float gracefully between feminine and masculine styling. It’s what you'd call “understated” if not for the fact that it’s a literal opal disc wrapped in diamonds. But the proportions keep things elegant—not aggressive. More discreet peacock, less Vegas headliner.
The bracelet—code D23 stamped on the caseback—is a work of art in itself, hand-finished with alternating rows of textured diamond-cut rectangles and high-polish bars. It’s tactile, detailed, and impossibly comfortable.
Powering the piece is Piaget’s manual-wind 9P2 movement, a follow-up to their groundbreaking ultra-thin 9P. If you know, you know. This watch has the soul of a dress watch but the brains of an haute horlogerie pioneer.
Condition? Mint. Stones are intact—no cracks in the onyx (which is no small feat, as carving a single, thin ring of onyx without splitting it is more difficult than explaining cryptocurrency to your parents).
If you’re the type who sees a little mystery in your wardrobe—a signal to the ones who get it—this Piaget has been transmitting for decades. All you have to do is pick up.
