Historical significance
Mido Ocean Star 39 mm Green Platinum sits within Mido's Ocean Star line, introduced in 1988. It carries the house codes established since 1918 — platinum 950 case, green sunburst dial and automatic, 38-hour reserve — 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.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
