Rolex Lady-Datejust 31 31 mm 278243DGRDVIO Steel/Yellow Gold Grey

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history. Introduced in 1957 as the first self-winding waterproof wristwatch sized specifically for women, the Lady-Datejust has evolved through decades of refinement while preserving the instantly recognizable architecture that made it a landmark design. Today the 31mm case sits at an ideal midsize proportion—substantial enough to read with authority on the wrist yet refined enough to complement any style of dress.

Reference 278243DGRDVIO belongs to the current generation of the Lady-Datejust 31, pairing Rolex's proprietary Oystersteel with 18k yellow gold in a combination the brand calls Rolesor. The two-tone construction is executed with characteristic precision: yellow gold crowns the domed bezel, frames the lugs, and runs through the alternating center links of the Oyster bracelet, while the cool-toned Oystersteel case and outer bracelet links provide a grounding counterpoint that keeps the watch from reading as overtly flashy.

The grey dial is the quiet star of this reference. Grey occupies a rare position in dial design—it reads as neutral without being colorless, sophisticated without demanding attention. Against the warm yellow gold of the domed bezel it creates a considered tonal contrast, and depending on the light it can shift from a deep slate to a luminous silver. The combination is universally flattering and pairs with virtually any metal jewelry already on the wrist.

Powering the watch is Rolex's automatic movement, a self-winding caliber that reflects the brand's longstanding commitment to in-house manufacture, precision, and reliability. The Oyster case, with its screw-down crown and 100-meter (330-foot) water resistance, ensures that the movement is protected from moisture, dust, and pressure, making this watch fit for everyday wear without compromise. The Oyster bracelet itself features the Oysterclasp, Rolex's secure and easy-to-operate folding clasp.
