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. There is a certain dignity that can only be found in a rectangular case. Something that no round case can replicate and no odd shape can imitate. The Cartier Tank is often the first to come to mind, but many others have played the rectangular game and came out equal to, or more interesting than Cartier, at least in our opinion. This ultra-thin, 18k yellow gold Piaget with a clean black dial is a faultless example.

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.

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.
