Catalogue description
Dealer description — Vintage Watch Specialist
A Striking Vintage Tissot Seastar Navigator Chronograph in Superb Original Condition and Attractive Lume, c. Introduced in the 1950s, the Tissot Seastar line quickly became known for blending elegant design with practical water resistance, making it a versatile choice for everyday wear. Evolving over the decades, the Seastar family expanded from classic dressy waterproof watches into robust divers, reflecting changing tastes and technical advances. From slim vintage models with understated charm to modern professional dive tools, the Seastar range highlights Tissot’s ability to combine Swiss precision with accessible, stylish functionality. What's on Offer We are delighted to offer this superb vintage Tissot Seastar Navigator Chronograph for sale in such superb vintage condition — a tool watch with serious wrist presence. Housed in a brushed stainless steel tonneau case showing only light, honest wear, this watch combines robust charm with functional versatility. The bold black dial features two counters: a 30-minute register and a continuous seconds subdial. Framed by a rotating tachymeter bezel, it allows for measuring speed over distance. Twin pushers operate the chronograph functions while a subtle date aperture at 6 o’clock completes the layout. With its sharp looks, practical complication, and vintage appeal, this is a fantastic example of Tissot’s golden era of chronographs.
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
Chronographs and split-seconds watches
A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.
Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.
What to look for
- Push-pieces on the case band or a single button in the crown (monopusher).
- Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
- Column wheel versus cam control visible in the movement.
- Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).
Dating clues
- Pocket chronographs with heart cam reset: after 1862.
- Wrist chronographs: from c. 1910; two-button designs from the 1930s.
- Automatic chronographs: from 1969.
