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
Omega Seamaster 40 mm Ice Sapphire sits within Omega's Seamaster line, introduced in 1964. It carries the house codes established since 1848 — sapphire crystal case case, ice blue dial and in-house manual-winding — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- 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.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Omega has spent more than 178 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Speedmaster, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis Brandt established Omega in 1848, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Omega calibre produced today.
