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
Baume & Mercier Linea 37 mm Mother-of-pearl Quartz sits within Baume & Mercier's Linea line, introduced in 1958. It carries the house codes established since 1830 — quartz tpt case, mother-of-pearl dial and high-beat automatic — 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
Baume & Mercier has spent more than 196 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Clifton, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis-Victor & Célestin Baume established Baume & Mercier in 1830, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Baume & Mercier calibre produced today.
