Historical significance
Casio Oceanus 42 mm Skeletonised Carbon sits within Casio's Oceanus line, introduced in 1982. It carries the house codes established since 1946 — carbon tpt case, skeletonised dial and high-accuracy quartz — 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
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.
