Product Description
Piaget Ref.9155 — The Geometry of Light and Shadow.

There are watches that tell time — and there are watches that sculpt it.
This Piaget Ref.9155 belongs to the latter.

Born in the 1980s, an era when Piaget stood at the crossroads of design and jewelry, this piece transforms timekeeping into architecture.
Its 35×28mm case in 18K white gold is a study in symmetry, where every angle, every facet, seems drawn by a master architect of light.

The dial is a breathtaking composition of black onyx and pavé-set diamonds, arranged in alternating vertical stripes — a dialogue between light and shadow, precision and poetry.
Each onyx segment absorbs light into infinite depth, while the diamonds scatter it back with mesmerizing brilliance.
It's a silent rhythm, like the alternating beats of night and day frozen into gold.

Inside, a hand-wound movement reminds us that even in a world of extravagance, Piaget never abandoned the craft.
The crown winds with quiet resistance, connecting you to the mechanical heart behind this jeweled façade.
It's a reminder that beneath the glamor lies pure horological discipline.

The watch rests on its original black strap with a signed Piaget buckle, offering a tactile contrast between the smooth onyx surface and the cold white gold case.
It's not about sparkle; it's about presence — the quiet confidence that defines true luxury.

Piaget's creations from this era embody what we now call “Architectural Elegance.”
Their watches weren't designed to follow trends, but to define space — to frame time itself.
And this Ref.9155, with its hypnotic vertical geometry, is one of those rare designs that blurs the line between sculpture and watchmaking.

Box included, original belt, no cracks — a pristine survivor of an era when craftsmanship and daring design coexisted in perfect proportion.
A watch for those who understand that real elegance lives in silence, symmetry, and light
