What is a DateJust Watch?
What is a DateJust watch?
The DateJust is without a doubt one of the most iconic watches in the world. Launched by Rolex in 1945, the Rolex DateJust actually only shows the date in a window at 3 o'clock on the dial. This unique combination was further improved in 1953 with the magnifying effect of the Cyclops lens (extra curvature on your glass plate). The DateJust watch was the first automatic wristwatch to automatically change the date exactly at midnight. This innovative design changed the world of watchmaking forever. And so the iconic Rolex Datejust was born.
A Rolex Datejust doesn't tell time. It tells a story.
How did the DateJust get its name?
The name 'DateJust' comes from the word 'Date' and the word 'Just'. 'Date' literally means: date. And 'Just' comes from the fact that the watch always shows the date correctly and on time, which seems like a small detail, but was revolutionary in 1945. Today, the model remains popular thanks to its beautiful design and unmistakable appearance.
Wearing a Datejust is not about checking the hour, it's about owning the moment.

The History of the DateJust
The DateJust was introduced in 1945 to celebrate Rolex’s 40th anniversary. It was immediately praised for its unique date function, integrated into an elegant and functional case. Later, the signature ‘Cyclops lens’ above the date window was introduced, making it easier to read the date. Over the years, the DateJust has been updated several times, with improvements to both the movement and the aesthetics. Nevertheless, the watch has always retained its classic DNA.
