Catalogue description
Dealer description — Vintage Watch Specialist
A Very Striking and Increasingly Collectable Tissot Automatic Navigator Seastar T.12 with a Stunning Two-Tone Dial, c.1970 The Tissot Seastar line debuted in the 1950s, blending elegant design with robust water resistance, making it a versatile choice for both dress and sport. Over the decades, it evolved to include diving and world time models, like the Navigator T12, reflecting Tissot’s commitment to innovation and accessible Swiss craftsmanship. What's on Offer We're thrilled to present this very recently serviced, Tissot Navigator Seastar T12, a truly striking vintage world timer dating to around 1970, and a fantastic example of Tissot’s talent for functional design with a bold aesthetic twist. Housed in a solid polished stainless steel case, this is a watch built for globetrotters and design aficionados alike. The real star of the show is the two-tone dial, which cleverly divides the 24-hour scale into contrasting day and night segments, allowing for easy tracking of multiple time zones via the rotating inner bezel, operated by the second crown. The crisp city ring, with destinations from Greenwich to Auckland, completes the classic 1970s travel aesthetic, while the zingy orange seconds hand and minimalist rectangular hour markers lend a punch of modernist flair. Powered by the reliable Tissot Calibre 788, a 21-jewel automatic movement with a 45-hour power reserve, this piece is running beautifully and comes in superb preowned condition. The steel bracelet is also in good shape. This is certainly no wall flower and and is sure to pique the interest of many with its solid presence on the wrist. A worthy addition to any collection.
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.
