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
Mido Ocean Star 39 mm Ice Quartz sits within Mido's Ocean Star line, introduced in 2011. It carries the house codes established since 1918 — quartz tpt case, ice blue dial and quartz — 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.

Brand history
Mido has spent more than 108 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Ocean Star, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Georges Schaeren established Mido in 1918, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Mido calibre produced today.
