Rolex 278344rbr-0020 Datejust 31mm Stainless Steel – White Gold Diamond Jubilee Mint Green Dial Watch

Rolex Datejust 31 — Reference 278344RBR-0020

Introducing the exquisite Rolex Datejust 31 ref. 278344RBR-0020, a refined embodiment of Rolex’s mastery in combining gem-set artistry with technical precision. With a 31 mm White Rolesor case, domed diamond bezel, and graceful mint-green dial, this timepiece radiates fresh elegance and enduring sophistication.

Case & Construction

The case is rendered in White Rolesor, Rolex’s signature combination of Oystersteel and 18 ct white gold — offering both durability and luminous beauty. Measuring a balanced 31 mm across, the case follows Rolex’s Oyster architecture: monobloc middle, screw-down back, and a Twinlock winding crown ensure water resistance to 100 meters / 330 feet. Over the dial rests a domed, diamond-set bezel, forming a halo of brilliance that frames the dial with refined sparkle. The dial is protected by a scratch-resistant sapphire crystal with the signature Cyclops lens magnifying the date window at 3 o’clock.

Dial & Distinctive Elements

One of the standout features of ref. 0020 is its mint-green sunray dial, which bathes the face in fresh, luminous tones. The sunray texture ensures that light plays elegantly across the surface, creating subtle gradients and depth. Applied stick (baton) hour markers and sleek polished hands deliver a clean, legible aesthetic suited to the dial’s soft hue. At 3 o’clock, the date aperture is enhanced by Rolex’s Cyclops magnification for easy reading. The harmonious contrast between mint-green dial and diamond bezel gives the watch a luminous yet composed presence.

Movement & Performance

Driving the ref. 278344rbr-0020 is Rolex’s in-house Calibre 2236, a self-winding mechanical movement designed for high precision. It offers a power reserve of approximately 55 hours, balancing performance with practicality. Rolex certifies the completed watch under its Superlative Chronometer standard, meaning it runs within –2/+2 seconds per day after casing. The movement employs advanced technologies — including instantaneous date change and a stop-seconds function — to ensure reliability, precise setting, and long-term stability.

Bracelet & Wearability

This model is offered with Rolex’s classic Jubilee bracelet, composed of flexible five-piece links in Oystersteel for a refined and comfortable fit. It closes via the concealed folding Crownclasp, preserving an elegant, uninterrupted bracelet profile. Together, the 31 mm case dimension and Jubilee bracelet ensure the watch maintains graceful proportions on a variety of wrist sizes.
