Designer
Emmanuel Gueit
Emmanuel Gueit came from a family of Geneva jewellers and was barely into his twenties when he drew the oversized Royal Oak Offshore in 1993 — a watch the house's traditionalists resisted and collectors turned into an icon.
Historical significance
Tissot Gentleman 42 mm Mother-of-pearl Sapphire sits within Tissot's Gentleman line, introduced in 1981. It carries the house codes established since 1853 — sapphire crystal case case, mother-of-pearl dial and automatic powermatic 80 — 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.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
