Catalogue description
Dealer description — Craft & Tailored
Piaget is widely celebrated as 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. Dating to the late 1970s and executed in 18k white gold, this exceptional Piaget is a compelling expression of the brand’s refined craftsmanship and design philosophy. Its defining feature is an elegant dual-time display, achieved through opposing Cal. 6P1 movements and presented via contrasting silver and black sub-dials, each adorned with classic Breguet numerals and set within a finely executed guilloché dial. A crisp hobnail-patterned bezel frames the composition, incorporating two slim crowns at 3 and 9 o’clock for intuitive operation. Completing the dial is the Asprey signature at 6 o’clock, an enduring symbol of London luxury since 1847 and a storied retailer to royalty, celebrated for commissioning exceptional pieces from the world’s most prestigious watchmakers. This combination of an Asprey-signed guilloché dial, dual-time display, and elegant detailing results in a harmonious and highly collectible timepiece that is rooted in functionality.

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
Military, pilot and travel watches
The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.
In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.
What to look for
- Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
- High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
- 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
- Wire lugs on early wristlets converted from pocket watches.
Dating clues
- Wire-lug wristlets: c. 1900–1925.
- Military specifications of the Second World War: 1939–1945.
- GMT and world-time wristwatches: mainly after 1950.
