  • Instantaneous date mechanism: The date instantly switches to the next date at midnight rather than rolling over slowing over the course of a few hours
  • Rapid setting: More commonly known as quickset, this means that the date can be set independently from the time
  • Stop-seconds: More commonly known as hacking, this means that the seconds hand comes to a complete stop when the winding crown is pulled out for precise time setting
  • Cyclops: The bubble-like lens that protrudes from the crystal above the date window to magnify it
  • Oyster case: The specific case structure that Rolex has been using since 1926 to ensure optimal water resistance that includes a screw-down winding crown and screw-down fluted caseback
  • Perpetual movement: The self-winding movement with a Perpetual rotor that Rolex first introduced in 1931. Any Rolex that has “Perpetual” written on the dial is an automatic watch
  • Oyster Perpetual: A Rolex watch that combines a water-resistant Oyster case and automatic Perpetual movement
  • Everose gold: Rolex’s proprietary 18k rose gold alloy that’s mixed with copper for color and platinum for fade resistance
  • Rolesor: The combination of stainless steel and gold on a Rolex watch. It can be called Yellow Rolesor, White Rolesor or Everose Rolesor depending on the particular shade of gold used
  • Jubilee Bracelet: Rolex’s five-link metal bracelet with semi-circular links
  • Oyster Bracelet: Rolex’s three-link metal bracelet with flat links
  • President Bracelet: Rolex’s precious metal three-link metal bracelet with semi-circular links
  • Easylink: The extension link fitted to some clasps to allow the wearer to easily adjust the length by 5mm

Brief History of the Rolex Datejust

Rolex introduced the Oyster Perpetual Datejust in 1945 to celebrate the brand’s 40th anniversary. The Datejust brought together two Rolex innovations from the prior two decades—the Oyster case and the Perpetual movement—and combined it with a date indication. The Datejust made history as the first automatic chronometer wristwatch to display the date via a window on the dial. The watch featured a 36mm case in yellow gold and it was topped with a fluted bezel. This was also the Rolex watch model that debuted the now-famous Jubilee bracelet.

Vintage Datejust without Cyclops or DATEJUST on the dial

Within a decade of its introduction, Rolex enhanced the Datejust in a few important ways. First, in 1953, the Cyclops magnifications lens was affixed to the exterior of the crystal to make the date window more legible. Then, by 1955, the date mechanism was updated to instantly switch to the next day at midnight. Also in the mid-1950s, the name DATEJUST became a permanent fixture on the dials. Finally, near the end of the decade, the Datejust silhouette moved away from the “bubble back” caseback towards a flatter shape due to a redesigned movement with a flatter rotor. These features are still an integral part of Rolex Datejust watches today.

In 1953, Rolex furnished the Datejust with the option of a “Turn-O-Graph” rotating timing bezel. The Datejust Turn-O-Graph models quickly became known as the Rolex “Thunderbird” once they were appointed as the official watch of the US Air Force Thunderbirds Squadron. The Turn-O-Graph bezels remained an option of the 36mm Datejust until it was discontinued in 2011.

To accompany the men’s Datejust watch, Rolex added the Lady-Datejust to the collection in 1957. The Oyster Perpetual Lady-Datejust included the key features of the original Datejust but with a smaller 26mm case.

Over the next decades, Rolex continued to improve the movements powering the watches, which led to new Datejust reference families. A particularly significant development was the addition of the quickset feature in the late-1970s, which allowed the date to be adjusted without having to continuously turn the hands around the dial to pass midnight. It’s also important to note the launch of the quartz-powered models called the Oysterquartz Datejust in 1977.

The Cyclops lens magnifies the date 2.5 times

Along with new movements, the Datejust collection also expanded to include new material options, sizes, and style variations in bezels, bracelets, and dials.

From quickset vs. non-quickset to acrylic vs. sapphire, it is important to understand the differences between the various generations of the 36mm Datejust before deciding which one would work best for you.

The Lady-Datejust and the Datejust 31 are the only Datejust models that offer the option President bracelets as well as platinum references. What’s more, many of the Datejust watches for women offer the choice of lavish diamond embellishments including diamond-set bezels, dials, cases, and bracelets.
