Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Rado Hyperchrome 39 mm Slate Platinum sits within Rado's Hyperchrome line, introduced in 1965. It carries the house codes established since 1917 — platinum 950 case, slate grey dial and quartz — 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 movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Rado has spent more than 109 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Captain Cook, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Fritz, Ernst & Werner Schlup established Rado in 1917, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Rado calibre produced today.
