Rolex 278240-0016 Datejust 31mm Stainless Steel Jubilee Dark Grey Dial Watch

Rolex Datejust 31 — Reference 278240-0016

Introducing the elegant Rolex Datejust 31 ref. 278240-0016, a refined expression of Rolex’s design ethos. With its 31 mm case in stainless steel, dark grey sunray dial, domed bezel, and Jubilee bracelet, this model harmonizes classic proportions with contemporary flair.

Case & Exterior Design

The case is constructed in Oystersteel, Rolex’s proprietary 904L-grade steel alloy known for superb corrosion resistance and long-lasting polish. Its 31 mm diameter is designed to offer a presence that is elegant yet substantial. A domed bezel (smooth profile rather than fluted) frames the dial, giving a gentle curvature that flows into the lugs and adds visual softness. The Oyster case architecture (monobloc middle, screw-down back, Twinlock crown) ensures water resistance to 100 m (330 ft). The sapphire crystal above the dial includes Rolex’s Cyclops lens to magnify the date display for clarity.

Dial & Readability

At its heart, the 278240-0016 features a dark grey sunray dial with radial brushing that creates subtle, shifting light play across its surface. The sunray texture gives the dial depth while maintaining a versatile, neutral aesthetic. Applied Roman numerals in 18 ct white gold mark the hours, lending a classic touch to the dial. The date is shown at 3 o’clock, enlarged by the Cyclops lens for quick reading. The contrast between the dial and indices ensures that the watch reads cleanly at a glance, even in varied lighting.

Movement & Technical Excellence

Inside, the Calibre 2236 powers the 278240-0016 — Rolex’s self-winding mechanical movement known for durability and precision. It offers a power reserve of approximately 55 hours, providing flexibility even if the watch isn’t worn daily. The movement features Rolex’s innovations such as the Syloxi silicon hairspring, Paraflex shock absorbers, and instantaneous date change — all traits that contribute to reliability and performance under varying conditions. Rolex certifies the assembled watch under the Superlative Chronometer standard (–2/+2 sec/day).

Bracelet & Wearability

278240-0016 comes fitted with the Jubilee bracelet, composed of supple five-piece links — a design that balances elegance and comfort. The clasp is a concealed folding Crownclasp, preserving a clean, seamless look when closed. Between the size, bracelet design, and finishing, the watch wears gracefully on a wide range of wrist sizes.

Unique Features & Appeal

• The domed bezel offers a softer, more understated frame than fluted alternatives — ideal for those who appreciate subtlety in design.
• The dark grey sunray dial grants the watch a modern neutrality, shifting beautifully with light.
• Stainless steel (Oystersteel) construction affirms robustness and daily wearability without sacrificing refined aesthetics.

In sum, the Rolex Datejust 31 ref. 278240-0016 is a refined timepiece embodying Rolex’s timeless design language and modern technical mastery. From its softly domed bezel to the elegant grey dial and reliable movement, this watch delivers quiet luxury with enduring performance — a choice that moves effortlessly between everyday elegance and elevated occasions.
