Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Montblanc 1858 36 mm Silvered 18k sits within Montblanc's 1858 line, introduced in 2010. It carries the house codes established since 1906 — 18k white gold case, silvered opaline dial and automatic chronograph — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- 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
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.
