Piaget 9131 Lapis Lazuli 1970s

Piaget 9131 Lapis Lazuli 18k White Gold, 1970s - Hardstone dial. Ultra-thin movement. Geometric perfection. This extraordinary Piaget, reference 9131 A6, is a sculptural expression of the brand’s elegant boldness in the 1970s — where haute joaillerie met ultra-thin horology. Crafted entirely from 18k white gold, the watch features an architectural case and seamlessly integrated bracelet, flowing effortlessly around the wrist with refined geometry. Its star feature? A flawless natural blue lapis lazuli dial, untouched and vivid, with the signature flecks of gold pyrite characteristic of this rare stone. Framed by a minimalist white gold bezel and paired with an elegant dauphine handset, the effect is deeply refined yet undeniably eye-catching. Inside ticks the legendary Piaget Caliber 9P, introduced in 1957 as the world’s thinnest manual-wound movement at just 2mm. This technical feat allowed Piaget to pair hardstone dials like this with ultra-slim cases — a hallmark of the Maison's daring innovation. - wrist size in our picture is 18cm circumference - DIAL: original never touched blue Lapis Lazuli stone dial in flawless condition original hands and crown BRACELET & CLASP: the original Piaget integrated 18k white gold bracelet with bark finishing is fitting up to 18 cm wrist size and is NOT adjustable / 1.8 mm thick for bracelet adjustments a goldsmith is needed 18k gold Piaget clasp with Piaget logo CASE: great overall condition, showing very minor traces of use 3- body 18k white gold case with screw-down case back 23 mm (without crown) / 23 mm (lug-to-lug) / 23 mm (between lugs) / 5 mm thick Year: 1970s reference: 9131 A6 total weight: 89 g MOVEMENT: Piaget Cal. 9P - manual wind 18 jewels, 19800 A/h, 36 hours power reserve professionally serviced 05/2026 -4 sec/d / 280° BOX & PAPERS: GOLDAMMER box GOLDAMMER certificate of authenticity and GOLDAMMER service documentation card GOLDAMMER REFERENCE: #1608
