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 Iced Sea 37 mm Salmon 18k sits within Montblanc's Iced Sea line, introduced in 2020. It carries the house codes established since 1906 — 18k white gold case, salmon 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
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.
