Historical significance

Baume & Mercier Linea 44 mm Mother-of-pearl 18k sits within Baume & Mercier's Linea line, introduced in 2015. It carries the house codes established since 1830 — 18k white gold case, mother-of-pearl dial and spring drive — 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 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.
