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
Casio Pro Trek 40 mm Ice Platinum sits within Casio's Pro Trek line, introduced in 2002. It carries the house codes established since 1946 — platinum 950 case, ice blue dial and eco-drive solar quartz — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- 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.

Brand history
Casio has spent more than 80 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's G-Shock, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Tadao Kashio established Casio in 1946, working from Japan at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Casio calibre produced today.
