The Rolex Lady-Datejust reference 279383RBR-0018 is a 28mm luxury timepiece crafted in Yellow Rolesor, a signature combination of Oystersteel and 18k yellow gold. This model is distinguished by its sunray silver dial, which features 18k yellow gold settings for diamond hour markers to prevent tarnishing. The watch is further elevated by a fixed bezel set with 46 brilliant-cut diamonds and is paired with a three-piece link Oyster bracelet. It utilizes a scratch-resistant sapphire crystal with a Cyclops lens over the date window and a screw-down Twinlock winding crown to ensure water resistance up to 100 meters.

Powered by the in-house caliber 2236, this self-winding mechanical movement offers a precision of -2/+2 seconds per day and is a COSC-certified chronometer. Its complications include central hands for hours, minutes, and seconds, along with an instantaneous date display with a rapid-setting feature. The movement also incorporates a stop-seconds function for precise time setting and is equipped with a Syloxi hairspring in silicon for increased stability against temperature variations and shocks.

General reviews of this reference emphasize its blend of classical elegance and modern technical performance. Collectors frequently praise the aesthetic balance between the radiant diamond-set bezel and the versatile silver dial, noting that the Yellow Rolesor construction provides a prestigious look suitable for both formal and everyday wear. While the 28mm case size is celebrated for its feminine and delicate proportions, it is also noted as a robust choice for a daily-wear luxury watch due to its durable Oystersteel components and reliable movement.
