Historical significance
Tissot Chemin des Tourelles 44 mm Mother-of-pearl Quartz sits within Tissot's Chemin des Tourelles line, introduced in 1955. It carries the house codes established since 1853 — quartz tpt case, mother-of-pearl dial and quartz — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- 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.
