Understanding Vintage Rolex Oyster Perpetual Date References
Rolex reference numbers help determine the era, case style, and configuration of the watch. Four-digit Rolex references were produced mainly between the late 1950s and late 1970s. These watches represent the classic vintage Rolex era.
Five-digit references followed during the late 1970s, 1980s, and 1990s, offering slightly improved movements and bracelets while maintaining the traditional design language. Both generations remain widely available on Wristler and represent some of the most approachable vintage Rolex models.
The primary differences between the date and no date variant are the date variant features a date window with a magnifying Cyclops lens and a date-equipped movement. We’ve also written a guide about vintage Oyster Perpetual without date function for you.
