Historical significance
Tissot Seastar 36 mm Mother-of-pearl Carbon sits within Tissot's Seastar line, introduced in 1966. It carries the house codes established since 1853 — carbon tpt case, mother-of-pearl dial and automatic cosc chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
