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
Rolex Explorer 38 mm Green Platinum sits within Rolex's Explorer line, introduced in 1954. It carries the house codes established since 1905 — platinum 950 case, green sunburst dial and in-house automatic, chronometer certified — 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Rolex has spent more than 121 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Submariner, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Hans Wilsdorf established Rolex in 1905, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Rolex calibre produced today.
