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

Montblanc Star Legacy 37 mm Mother-of-pearl Ceramic sits within Montblanc's Star Legacy line, introduced in 2010. It carries the house codes established since 1906 — ceramic case, mother-of-pearl dial and automatic, swiss lever escapement — 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.
  • 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

Montblanc has spent more than 120 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's 1858, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

August Eberstein, Alfred Nehemias & Claus-Johannes Voss established Montblanc in 1906, working from Germany at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Montblanc calibre produced today.
