Designer

Tissot 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 PRX 38 mm Black Stainless sits within Tissot's PRX line, introduced in 1994. It carries the house codes established since 1853 — stainless steel case, black lacquer dial and automatic, 38-hour reserve — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • Early production dials show a slightly different minute track, and collectors pay a premium for them.
  • The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
  • The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
