Rolex Lady-Datejust 28 Yellow Rolesor — Silver Roman Dial | Ref. 279163

The Lady-Datejust 28 reference 279163 distils over seven decades of Datejust heritage into a 28 mm Oyster case of exceptional refinement. In yellow Rolesor — the harmonious pairing of Oystersteel with 18 ct yellow gold on the fluted bezel, crown and Jubilee bracelet centre links — this watch presents a silver dial with elegant Roman numeral hour markers that evokes the classical watchmaking tradition Rolex has championed since 1945. Slender, perfectly proportioned and supremely legible, the Lady-Datejust remains the definitive ladies' dress watch from Geneva.

The 279xxx series Lady-Datejust is equipped with the Calibre 2236, Rolex's latest self-winding manufacture movement designed specifically for the 28 mm case diameter. The 2236 represents a substantial technical advancement: it incorporates a Syloxi silicon hairspring — produced using micro-mechanical fabrication techniques — providing outstanding resistance to magnetism and temperature variation. The movement achieves a 55-hour power reserve, Superlative Chronometer accuracy of ±2 seconds per day, and is regulated in five positions. The date changes instantaneously and is magnified 2.5× by the patented Cyclops lens. Water resistance is rated to 100 metres.

Reference 279163 in yellow Rolesor with a Roman silver dial occupies a perennially desirable position within the Lady-Datejust family. Its versatility is unmatched — equally at home against a boardroom ensemble as at a formal evening event — while the yellow gold accents provide warmth that flatters a wide range of skin tones. For collectors building a comprehensive modern Rolex holding, or for the first-time buyer seeking a watch that will be worn and treasured for decades, the reference 279163 offers horological substance and timeless elegance in ideal measure.
