Catalogue description
Dealer description — Craft & Tailored
Piaget is widely celebrated as being one of the most creative and esoteric watchmakers, with a deep foundation in Swiss watchmaking as the brand was established in 1874. The avant-garde approach to design isn't without a rigorous dedication to quality, which is expressed through the brand's inherent comprehension of what high luxury and fine watchmaking truly are. The ref. 9025 B2 is a true representation of the Piaget design ethos in the 1970s, with the melding of precious materials and brilliant stones which are then finished to a degree that is now all but lost in watchmaking. The result is a stunning and extremely thin seamless integrated bracelet design with an incredible onyx stone and pave diamond 'mystery' dial. Piaget is also known for being a mechanical powerhouse as well and this ref. 9523 D2 employs the in-house cal. 9P2 mechanical winding movement. SPECS Stock # PG9025B2 Brand Piaget Style Cocktail "Mystery" Dress Watch Model 9025 B2 Serial 31XXXX Size Unisex Material 18K Yellow Gold Dial Onyx Stone & Pave Diamonds "Mystery" Millimeters 30.5 Bracelet Piaget 18K Yellow Gold Integrated Bracelet CASE & BRACELET The classically round ultra-thin 18K yellow cold case is only 5mm thick and remains in excellent condition, exhibiting minimal signs of use and evidence of only gentle polishing in the past. The unsigned crown is believed to be original to the watch. The case back retains the factory engravings and hallmarks in very crisp and deep condition. The integrated 18K yellow gold mesh bracelet exhibits minimal wear or age and only subtle curving that is extremely common to see in this bracelet style in this era. The bracelet was previously sized to fit a larger wrist so additional 18K yellow gold material was added at the clasp to extend the bracelet, the bracelet currently fits a 7 3/4-inch wrist, but can be sized to fit any wrist size upon request. DIAL & HANDS The exquisite three-piece onyx stone and pave diamond dial is masterfully crafted and incredibly stunning. The onyx stone of the outer dial, along with the inner rotating onyx stone disc set with a single diamond which functions as the hour hand, exhibit no cracks and remain in virtually perfect condition. The center pave diamond portion of the dial is expertly set and also in perfect condition. The yellow dauphine minute hand, which is the only traditional hand on the dial, is in excellent condition with nominal oxidation present. ACCESSORIES None. The watch is keeping time, but the service history is unknown. A movement service can be provided upon request.
Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
