The Rolex Datejust is one of the most enduring watch designs in horological history, introduced in 1945 as the first wristwatch to display the date in a window on the dial. Over eight decades it has evolved through dozens of dial configurations, case sizes, and material combinations, yet the fundamental proportions and instantly recognisable silhouette have remained constant. The 31 mm case size — known as the Datejust 31 — occupies a refined middle ground that suits a wide range of wrists and has become one of the most sought-after configurations in the modern Datejust lineup.

Reference 278344RBRGDO is finished in Oystersteel, Rolex's proprietary 904L stainless steel, combined with 18k white gold accents that elevate the piece into the luxury tier. The 31 mm Oyster case is robustly proportioned yet delicate enough for formal wear, and its water resistance of 100 metres (330 feet) underscores the practical engineering beneath the jewellery-grade exterior. The Oyster bracelet mirrors the case's two-tone character and lends a secure, polished fit on the wrist.

The dial of the 278344RBRGDO is a striking dark grey set with diamonds, creating a depth and luminosity that shifts with changing light. Diamond hour markers catch and scatter ambient light in a way that printed indices simply cannot replicate, giving the dial an animated, almost three-dimensional quality. Complementing this is the domed bezel set entirely in 18k white gold with diamonds, a configuration Rolex designates with the RBR suffix, denoting its brilliant-cut diamond setting.

Powering the watch is a Rolex automatic movement housed within the Oyster case. The crown-winding system and the screw-down Twinlock crown contribute to the water resistance and overall durability that have made the Datejust a trusted daily companion for generations of wearers. The movement oscillates via a Perpetual rotor, keeping the watch wound through normal wrist motion and requiring no manual winding under regular wear.

On the wrist, the 278344RBRGDO projects quiet confidence — it is neither understated nor ostentatious, but occupies that luxury sweet spot where fine materials and precise engineering meet effortless wearability. The dark grey diamond dial reads crisply in all lighting conditions, while the diamond bezel adds brilliance without overpowering the design. It is a watch that transitions naturally from a boardroom setting to an evening occasion.

Bizak and Co. specialises in pre-owned and new luxury timepieces, offering knowledgeable service and transparent descriptions to help you buy with confidence online. The Rolex Datejust 31 reference 278344RBRGDO is a compelling acquisition whether you are adding to an existing collection or purchasing your first fine watch.

FAQ

1. What makes the Rolex Datejust 31 ref. 278344RBRGDO special?
Reference 278344RBRGDO combines Oystersteel and 18k white gold construction with a dark grey diamond-set dial and a fully diamond-set white gold domed bezel, a pairing that places it among the most jewellery-forward configurations in the Datejust 31 lineup. The RBR suffix in the reference number specifically identifies the brilliant-cut diamond bezel, distinguishing it from plainer or fluted bezel variants. The result is a watch that balances technical Rolex engineering with genuine fine-jewellery aesthetics.

2. What movement powers the Rolex Datejust 31 278344RBRGDO?
The watch is fitted with a Rolex automatic (self-winding) movement, wound continuously through the motion of the wearer's wrist via the Perpetual rotor. Manual winding is possible through the screw-down Twinlock crown when needed. Rolex does not publicly name the specific caliber in all retail contexts, so buyers should consult Bizak and Co. or a Rolex service centre for precise caliber details.

3. What is the case size of the Datejust 31 278344RBRGDO?
The case measures 31 mm in diameter, placing it in Rolex's mid-size Datejust category — larger than the classic 28 mm Lady-Datejust but more refined and compact than the 36 mm or 41 mm Datejust models. This size suits a broad range of wrist sizes and is popular with both women and men who prefer a more modest case diameter.

4. Is the Rolex Datejust 31 278344RBRGDO suitable for everyday wear?
Yes — while its diamond dial and bezel give it a distinct dress-watch character, the Datejust 31 is built to Rolex's Oyster standards with a water resistance of 100 metres (330 feet) and a robust Oystersteel case. The Oyster bracelet is designed for long-term comfort and durability. Many owners wear this reference daily, appreciating both its resilience and its ability to complement formal attire.

5. What dial and bezel materials are used on the 278344RBRGDO?
The dial is dark grey and set with diamond hour markers, providing a cool, sophisticated palette that contrasts beautifully with the brilliant diamonds. The bezel is crafted in 18k white gold and fully set with diamonds in a domed profile, indicated by the RBR designation in the reference number. Together, these elements account for the watch's premium positioning within the Datejust family.

6. Is the Rolex Datejust 31 278344RBRGDO a good buy, and how can I purchase it from Bizak and Co.?
The Datejust 31 in steel and white gold with a diamond bezel and diamond dial is consistently in demand on the secondary market, making it a considered choice for collectors and first-time luxury watch buyers alike. Its combination of iconic Rolex heritage, precious materials, and everyday wearability supports strong long-term desirability.
