Rolex Datejust 31 – Ref. 278344RBR-0030

The Rolex Datejust 31 Ref. 278344RBR-0030 stands as a testament to refined elegance and gem-set artistry in a signature Rolex form. Built in the White Rolesor combination of Oystersteel and 18k white gold, this model features a diamond-set bezel, a luminous dial variant, and Rolex’s dependable Calibre 2236 movement — all in a wearable 31 mm package. This reference is ideal for those who demand both aesthetic grace and mechanical excellence.

White Rolesor Case Gem-Set Bezel

The 31 mm Oyster case is crafted in Rolex’s corrosion-resistant Oystersteel, paired with an 18k white gold bezel delicately set with brilliant-cut diamonds. This White Rolesor design blends the durability of steel with the luster of gold, giving the watch prestige and resilience in everyday wear. The gem-setting is executed with precision, aligning each stone for uniform brilliance and structural security. The Oyster case architecture and Twinlock screw-down crown ensure reliable water resistance to 100 meters / 330 feet.

Radiant Dial Roman Numerals

Beneath the scratch-resistant sapphire crystal (with Rolex’s signature Cyclops magnifier over the date) lies a finely executed dial with applied Roman numerals, lending a classic and elegant look. The numerals are crafted in 18k white gold to prevent tarnishing and maintain brilliance over time. A sunray or lacquered finish enhances light play, while polished hands provide excellent legibility. The result is a dial that is both timeless and sophisticated, perfect for those who appreciate traditional watchmaking details.

Calibre 2236 — Precision Performance

At its core ticks the Rolex Calibre 2236, a self-winding mechanical movement incorporating the Syloxi silicon hairspring and Paraflex shock absorbers, engineered for stability and precision under daily use. After casing, it is certified a Superlative Chronometer, achieving –2/+2 seconds per day accuracy. The power reserve reaches approximately 55 hours, giving the wearer flexibility over multi-day wear.

Elegant Jubilee Bracelet

This Datejust 31 278344rbr-0030 is paired with the legendary five-piece link Jubilee bracelet, first introduced in 1945 for the Datejust collection. Crafted from Oystersteel, it provides exceptional comfort, flexibility, and a graceful drape on the wrist. The polished center links and satin-finished outer links create a sophisticated play of light, enhancing the watch’s jewelry-like presence. It is secured with a concealed Crownclasp for a seamless and refined look.
