Rolex Datejust 31 Everose Rolesor — Rose Dial with Roman Numerals | Ref. 278241

Among the most enduring expressions of Rolex's Datejust lineage, the 31mm Everose Rolesor configuration of reference 278241 achieves a harmony of materials that few watchmakers can claim to master. The Oyster case — a seamless fusion of Oystersteel and 18K Everose gold — carries its 31mm diameter with assurance, the domed 18K Everose gold bezel framing the scratch-resistant sapphire crystal and its signature Cyclops lens with effortless refinement. The Twinlock screw-down crown and solid case back ensure waterproofness to 100 metres, lending this quintessentially elegant piece genuine robustness.

At the heart of the dial, rose-toned lacquer meets the warm gleam of Roman numeral hour markers — a pairing that honours classical horology while asserting a distinctly modern sensibility. Each numeral is proportioned to the 31mm canvas with precise intent, ensuring legibility without sacrificing grace. The date aperture at 3 o'clock, magnified 2.5× by the Cyclops lens, integrates cleanly into the radial design. The matching Everose Rolesor Oyster bracelet, with its flat three-piece links alternating polished gold and brushed steel, reinforces the two-tone narrative across every surface.

Powering the 278241 is the Rolex Calibre 2236, a manufacture movement of exceptional sophistication for its compact dimensions. Beating at 28,800 vibrations per hour and endowed with a Syloxi silicon hairspring for superior resistance to magnetic fields and thermal variation, the Cal. 2236 delivers approximately 55 hours of power reserve alongside an instantaneous date display with rapid-setting functionality. A Parachrom hairspring is replaced here by the proprietary Syloxi component — an engineering distinction that underscores Rolex's commitment to precision at every scale. This is a Datejust 31 that commands both the boardroom and the evening, worn as confidently at one as the other.
