Elegant and Enduring Design

The 31 mm Oyster case of the Rolex Datejust 31 is crafted entirely from Oystersteel—a highly resistant stainless steel alloy used exclusively by Rolex. Known for its superior corrosion resistance and polished luster, Oystersteel ensures that the timepiece maintains its beauty even after years of wear. The domed bezel adds a smooth, graceful contour to the case, enhancing its minimalist aesthetic while preserving the Datejust’s instantly recognizable silhouette.

Black Dial with Roman Numerals

At the heart of this model lies a beautifully balanced black dial that radiates quiet strength and sophistication. The deep tone of the dial contrasts elegantly with the polished Roman numeral hour markers, giving it a refined and timeless look. Each numeral is crafted with meticulous precision, reflecting Rolex’s dedication to detail. The signature Rolex crown at 12 o’clock and the date display at 3 o’clock, magnified by the iconic Cyclops lens, complete the dial’s harmonious symmetry.

Oyster Bracelet: Comfort and Strength

The watch is fitted with the legendary Oyster bracelet, known for its robustness and enduring style. Composed of three-piece solid links, the bracelet offers exceptional comfort and strength, ideal for everyday wear. Its Oysterclasp with the Easylink comfort extension system allows the wearer to adjust the bracelet length by approximately 5 mm for a perfect fit. Polished and satin-brushed surfaces create a subtle interplay of light, underscoring Rolex’s attention to refined finishes.

Precision Movement: Caliber 2236

Powering the Datejust 31 Ref. 278240-0001 is the self-winding Rolex Caliber 2236, a movement entirely developed and manufactured in-house. Equipped with a Syloxi silicon hairspring, it provides exceptional resistance to magnetic fields, temperature variations, and shocks—ensuring unparalleled accuracy and reliability.
