Historical significance

Montblanc 1858 42 mm Mother-of-pearl Carbon sits within Montblanc's 1858 line, introduced in 1995. It carries the house codes established since 1906 — carbon tpt case, mother-of-pearl dial and automatic chronograph — 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.

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.
