Rolex 278344rbr-0013 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Silver Dial Watch

Rolex Datejust 31 — Reference 278344RBR-0013

Introducing the refined Rolex Datejust 31 ref. 278344RBR-0013, a timepiece that artfully blends Rolex’s gemsetting mastery with timeless design. This 31 mm watch, crafted in White Rolesor with a domed, diamond-set bezel, houses a silver sunray dial that quietly commands attention with elegance and poise.

Case & Material Composition

The case is built using White Rolesor — Rolex’s signature fusion of Oystersteel and 18 ct white gold — combining structural resilience with radiant refinement. The bezel is domed and set with diamonds, forming a halo of light that softens the silhouette and adds a whisper of glamour. Rolex’s Oyster architecture (monobloc middle case, screw-down case back, Twinlock crown) ensures water resistance up to 100 m (330 ft). A scratch-resistant sapphire crystal with a Cyclops lens over the date provides protection and enhanced legibility.

Dial & Aesthetic Details

The dial is finished in silver sunray, achieved by radial brushing that catches light to produce subtle, shifting reflections across the surface. Applied stick indices and polished hands provide a clean, minimal contrast against the luminous silver backdrop. The date is displayed at 3 o’clock, magnified by the Cyclops lens to ensure crisp readability.  The combination of a bright silver dial and the diamond halo bezel creates a refined balance of sparkle and clarity.

Movement & Technical Excellence

Packed inside is Rolex’s Calibre 2236, a self-winding mechanical movement entirely developed in-house. This calibre offers approximately 55 hours of power reserve. It incorporates Rolex’s Syloxi silicon hairspring, Paraflex shock absorbers, instantaneous date change, and a stop-seconds function for precise adjustment. After casing, Rolex certifies the watch under its Superlative Chronometer standard (-2/+2 sec/day).

Bracelet & Wearability

The 278344rbr-0013 is paired with the Oyster bracelet in Oystersteel, featuring robust three-piece solid links built for both elegance and comfort. The bracelet is equipped with a folding Oysterclasp and Rolex’s Easylink 5 mm comfort extension, enabling small adjustments in fit to accommodate wrist changes through the day. The 31 mm case size complements the thoughtful bracelet design, striking a balance between presence and grace.
