Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Tissot Seastar 40 mm Meteorite Quartz sits within Tissot's Seastar line, introduced in 1967. It carries the house codes established since 1853 — quartz tpt case, meteorite dial and automatic, 38-hour reserve — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Tissot has spent more than 173 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's PRX, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Charles-Félicien Tissot established Tissot in 1853, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Tissot calibre produced today.
