Piaget Oval Ellipse Onyx Black Dial Diamond Bezel Ref. 9826 – White Gold Elegance with Iconic Cal. 9P1

A rare creation from Piaget’s golden era, the Oval Ellipse Ref. 9826 combines the maison’s mastery of ultra-thin horology with the glamour of high jewelry design. Crafted in solid 18K white gold and adorned with a factory-set diamond bezel framing a rich onyx-black dial, this piece epitomizes refined 1970s–1980s Piaget elegance. More jewel than mere watch, yet housing the legendary Calibre 9P1, it is a discreet statement of wealth, taste, and technical finesse.

The Case – White Gold Brilliance & Diamond Radiance

The 23 x 28mm oval case is fashioned from solid 18K white gold, its elegant curvature highlighted by an original factory-set diamond bezel. The watch remains in excellent unpolished condition, with sharp case edges and well-preserved gold hallmarks—a rarity among vintage Piaget pieces. Its slim architecture underscores Piaget’s reputation as a pioneer of ultra-thin luxury dress watches.

Protecting the dial is a mineral crystal, while the original Piaget-signed white gold crown completes the elegant silhouette.

The Dial – Perfect Black Onyx Minimalism

The dial is executed in pure black onyx, the absence of markers or ornament emphasizing Piaget’s commitment to clean, minimalist luxury. It is immaculate and untouched—deep, glossy, and endlessly elegant. This austere beauty allows the diamonds of the bezel to sparkle all the more brilliantly.

Movement – Legendary Piaget Ultra-Thin Cal. 9P1

Inside beats the manual-winding Piaget Calibre 9P1, one of the most important ultra-thin movements in Swiss watchmaking. Recently serviced, it runs with excellent timekeeping and is offered with a one-year mechanical warranty. This legendary movement, measuring just 2mm thick, was central to Piaget’s reputation as the master of slim, high-jewelry timepieces.

Strap & Buckle

The watch is paired with a handmade black Belgian crocodile strap, complementing the onyx dial. Securing the piece is an original 18K white gold Piaget buckle—an essential detail for collectors seeking authenticity.

Why This Watch?

The Piaget Oval Ellipse Ref. 9826 is an exceptional blend of jewelry artistry and mechanical ingenuity. Its oval shape, diamond-set bezel, and flawless onyx dial are emblematic of Piaget’s design codes during the maison’s most glamorous era. The presence of the original Cal. 9P1, unpolished white gold case, and signed buckle elevate this piece into the realm of serious connoisseurship.

For collectors of haute horlogerie and vintage jewelry watches, this example is both rare and significant—a true showcase of Piaget’s dual mastery in diamonds and ultra-thin watchmaking.
