Catalogue description
Dealer description — Craft & Tailored
Piaget was established in 1874 and is widely celebrated as being one of the most creative and esoteric watchmakers, with a deep foundation in Swiss watchmaking. Their avant-garde approach to design was never without a rigorous dedication to quality, the combination of which is expressed through the brand's inherent comprehension of what high luxury and fine watchmaking truly are and should look like. This very stylish, yet subtle women's dress watch from the '70s is the perfect example of that. The Piaget in-house 'ultra-thin' caliber 9P1 is housed inside an also ultra-thin, 18k gold case with an integrated bracelet that wears remarkably well no matter the wrist size. It's a timeless piece from a highly-respected yet slightly under-the-radar brand, making it a fantastic option for any collection. SPECS Stock # PG9902G1 Brand Piaget Style Dress Watch 'Ultra-Thin' Model 9902 G1 Serial 25XXXX Size Men's/ Unisex Material 18K Yellow Gold Dial Gold W/ Roman Numerals Millimeters 22.5 X 22.5 Bracelet Piaget 18K YG Integrated Bracelet CASE & BRACELET The svelte ultra-thin 18K yellow gold case measures only 4.5mm thick and is very well-preserved, showing honest signs of gentle use and nominal evidence of being previously polished. The unsigned crown is original to the watch. The case back display light wear with the factory engravings remaining very deep and crisp. The integrated 18K yellow gold bracelet shows visually no stretch and will fit a 5 3/4-inch wrist. DIAL & HANDS The original gold sunburst dial features painted black Roman numerals and black leaf-style hands which create a striking and welcomed dark contrast to an otherwise fully gold watch for an overall very elegant aesthetic. The dial is in excellent condition, showing no age or obscene damage, though surface of the dial does exhibit some extremely subtle hand drag that is not visible to the naked eye. The black hands are in excellent condition with minor 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.
