Historical significance
Montblanc Star Legacy 43 mm Mother-of-pearl Stainless sits within Montblanc's Star Legacy line, introduced in 1996. It carries the house codes established since 1906 — stainless steel 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.

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.
