Rolex Datejust 278274 – History

Origins & Heritage

The Rolex Datejust has been a cornerstone of the brand since its debut in 1945, when it became the first self-winding wristwatch to feature an automatically changing date window. Over the decades, the Datejust evolved through numerous sizes, materials, and design refinements — always maintaining its position as Rolex’s most versatile and iconic everyday luxury watch.

The reference 278274 continues that lineage within the modern 31mm “Lady-Datejust” collection, representing the perfect blend of classic elegance, technical precision, and contemporary engineering. It embodies Rolex’s White Rolesor design — the combination of Oystersteel and 18k white gold — and captures the refined essence of the Datejust in a smaller, timeless format.

Launch & Design Evolution

The Rolex Datejust 278274 was introduced as part of Rolex’s latest generation of Lady-Datejust models in the late 2010s, replacing the earlier reference 178274. It features several key advancements in both aesthetics and performance:

• A slightly re-proportioned 31mm Oyster case with improved ergonomics

• A refined white gold fluted bezel, a hallmark of Rolex’s classic style

• Modernized dial options including silver, pink, dark rhodium, and sunburst blue with Roman numerals

• The upgraded Caliber 2236 movement — a next-generation automatic movement featuring Rolex’s Syloxi silicon hairspring for improved precision and magnetic resistance

The 278274 upholds the Datejust’s legacy of balancing formality with daily wearability, offering water resistance, reliability, and understated sophistication in one refined design.
