Designer

In-house design studio

The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.

Historical significance

Tissot Seastar 41 mm Silvered 18k sits within Tissot's Seastar line, introduced in 2007. It carries the house codes established since 1853 — 18k yellow gold case, silvered opaline dial and automatic, 38-hour reserve — 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.

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.
