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’s steel watches are manufactured from Rolex’s own 904L alloy, known as "Oystersteel” from 2018. Most commonly used in high-technology and in the aerospace and chemical industries, 904L steels are comparable to precious metals for their anti-corrosion properties and acquire an exceptional sheen once polished. In 1985, Rolex became the first watchmaking brand to use this steel from the 904L family for its cases.
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.
