Rolex introduced the Datejust in 1945 to celebrate its 40th anniversary, marking an important moment in watchmaking. It was the first self-winding wristwatch to display the date and change it automatically at midnight, bringing both convenience and innovation to wearers. This launch showed Rolex’s skill in creating advanced designs and made the Datejust a lasting symbol of accuracy and style.

Rolex offers the Datejust in four sizes to suit different wrist types: 28mm, 31mm, 36mm, and 41mm. The Lady-Datejust was initially introduced in the 1950s with a 26mm case, designed specifically for women with smaller wrists. In 2015, Rolex replaced the 26mm model with the 28mm Lady-Datejust, updating the size to align with modern preferences while retaining its refined and elegant style. The 28mm is ideal for women seeking a delicate yet sophisticated timepiece.

Rolex Datejust 31mm is another popular choice for women or anyone with smaller wrists. Its slightly larger size offers a balanced look, blending tradition with contemporary design. Many also consider the 31mm as part of the Lady-Datejust collection due to its widespread appeal among feminine wearers.

Rolex Datejust 36mm model is the original size introduced with the Datejust in 1945. It remains a classic option for both men and women, appreciated for its versatility and timeless elegance. This size perfectly bridges the gap between a traditional and modern wristwatch, making it a favorite across generations.

For those who prefer a bold statement, the Rolex Datejust 41mm provides a striking presence. Initially launched as the Datejust II in 2009, it was redesigned in 2016 into the slimmer Datejust 41, offering improved proportions and enhanced comfort while maintaining its commanding style. This modern size appeals to individuals looking for a contemporary and bold take on the iconic Datejust design.
