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 beautifully subdued dress watch from the '80s is the perfect example of that. The Piaget in-house caliber 12P is housed inside an ultra-thin, 18k gold case 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.

DIAL & HANDS The matte gold 'crosshair' dial is in amazing condition, showing only a few small marks, namely around the 4:30 position. The ultra-thin, original gold baton hands match the dial so well that they almost blend in at times, adding to the sleekness of the package. ACCESSORIES None.

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
Automatic (self-winding) watches
Self-winding watches use the wearer's motion to wind the mainspring. Abraham-Louis Perrelet and Breguet made 'perpétuelle' pocket watches with oscillating weights in the late eighteenth century, but the principle only became practical in the wristwatch. John Harwood patented a bumper automatic in 1923; Rolex's Perpetual rotor (1931) winding in one direction, and later bidirectional rotors (Eterna, Felsa Bidynator), established the modern form. Micro-rotors (Universal Genève, Buren) and peripheral rotors made automatic watches thinner.
What to look for
- A semicircular rotor turning 360° over the movement, or a 'bumper' weight that rebounds between springs.
- 'Automatic', 'Perpetual' or 'Self-winding' on the dial.
- A sealed screw-back case, since automatic watches are wound less often by the crown.
Dating clues
- Bumper automatics: 1923–c. 1955.
- Full rotors: from 1931 (Rolex); widespread after c. 1950.
- Micro-rotors: from 1954–1958.
