The Explorer II
Rolex presented the Oyster Perpetual Explorer II, dedicated to polar explorers, speleologists, and all those pushing the boundaries of exploration. The watch featured a distinctive 24-hour hand, an invaluable aid around the poles and beneath ground when you can't tell night from day.
Rolex launched the Sea-Dweller 4000, waterproof to a depth of 1,220 metres (4,000 feet).
Rolex became the first watchmaking brand to pioneer the use of 904L for the cases of all its steel watches. Most commonly used in high‑technology and in the aerospace and chemical industries, its excellent anti-corrosion properties are comparable to those of precious metals and it offers a final polish of exceptional sheen.
A new interpretation of the Lady-Datejust was launched, the Pearlmaster.
The year 1992 heralded the arrival of the Oyster Perpetual Yacht-Master. This new member of the Oyster family reinforced the ties between Rolex and the sailing world.
