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 Clifton 39 mm Slate Platinum sits within Baume & Mercier's Clifton line, introduced in 1958. It carries the house codes established since 1830 — platinum 950 case, slate grey dial and high-beat automatic — 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.

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.
