Rolex Datejust 26 Yellow Gold — Mother-of-Pearl Diamond Dial with Fluted Bezel | Ref. 179238

Reference 179238 is a Lady-Datejust in 18ct yellow gold with one of the most visually rich dial configurations in the 26mm lineup: a mother-of-pearl surface set with diamond hour markers, framed by a fluted yellow gold bezel. Mother-of-pearl dials occupy a distinct tier within Rolex's design vocabulary — each dial is technically unique, the organic iridescence of the shell ensuring no two pieces present identically in varying light. The 26mm Oyster case in solid yellow gold, combined with the diamond-set dial and fluted bezel, places this reference squarely within the jewellery watch category, though without sacrificing the functional legibility that defines all Datejust references.

The 179238 is driven by the Calibre 2236, Rolex's purpose-built ladies' movement. Introduced to replace the earlier 2235, the 2236 features the Syloxi silicon hairspring — a significant engineering advance that improves frequency stability across temperature variations and eliminates sensitivity to magnetic fields that can disrupt traditional metallic hairsprings. Certified as a Superlative Chronometer, the movement maintains accuracy to ±2 seconds per day. The all-yellow-gold construction extends to the President bracelet, which provides a comfortable, articulated fit and the prestigious three-link profile historically associated with the Day-Date.

For collectors, the 179238 in full yellow gold with mother-of-pearl represents a relatively accessible entry point into solid gold Rolex ownership compared to larger or more complicated references. The dial configuration — mother-of-pearl with diamonds — commands a premium over plainer alternatives but remains within reach for serious buyers. Gold Datejust watches across generations have demonstrated consistent secondary-market resilience, and the 26mm format appeals to those who favor genuinely compact proportions with maximum material presence on the wrist.
