Rolex 278344rbr-0019 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Mint Green Dial Watch

Rolex Datejust 31 – Ref. 278344RBR-0019

The Rolex Datejust 31 Ref. 278344RBR-0019 is a refined women’s timepiece that blends elegance, precision, and gem-set luxury. This model, crafted in Rolex’s signature White Rolesor (stainless steel and 18k white gold) with a diamond-set bezel and mint green dial, offers a striking balance of style and technical excellence. Its compact 31 mm size makes it perfect for wrists that appreciate sophistication without bulk.

White Rolesor Construction & Diamond Bezel

The case is built in Oystersteel, combined with an 18k white gold bezel finely set with 24 brilliant-cut diamonds — an illustration of Rolex’s gem-setting mastery. This “White Rolesor” pairing delivers the durability of steel with the luster of gold, offering both resilience and refined appeal. The diamonds are individually matched and set to catch light seamlessly around the bezel.

Mint Green Sunray Dial & Index Markers

Beneath the sapphire crystal (with the magnifying Cyclops over the date) lies a mint green sunray-finish dial. The sunray brushing technique generates a play of light across its surface, enhancing its visual depth. The hour markers are polished applied indices (stick markers) with luminous fill, providing clarity and contrast against the green backdrop. Slim dauphine hands complete the look with elegance and legibility.

Movement & Performance — Calibre 2236

Driving this watch is Rolex’s in-house Calibre 2236: a self-winding mechanical movement equipped with Syloxi silicon hairspring and Paraflex shock absorbers for enhanced stability and precision. Certified as a Superlative Chronometer, it achieves a tolerance of –2/+2 seconds per day after casing. The movement provides about 55 hours of power reserve, making it practical for daily wear or occasional rotation.

Bracelet & Comfort — Oyster Bracelet with Easylink

The 278344RBR-0019 comes with the sturdy Oyster bracelet, featuring three-piece solid links. It includes the Easylink 5 mm comfort extension link, which lets the wearer adjust the bracelet on the fly for extra comfort. The folding Oysterclasp ensures a secure and elegant fit. This combination of bracelet design and flexibility makes the watch suitable for daily use and long wear alike.
