Rolex Datejust 26 Yellow Gold — White Diamond Dial, Fluted Bezel | Ref. 179178

Reference 179178 is a Lady-Datejust in 18-carat yellow gold — one of the purest expressions of Rolex's commitment to precious metal watchmaking in its smaller case sizes. At 26 mm, this is a watch whose dimensions are guided entirely by elegance rather than wrist presence, and the combination of the fluted yellow gold bezel with a white diamond-set dial produces an effect of considerable refinement. Every surface catches light differently: the fluted bezel scatters it, the diamond indices absorb and return it, and the polished case flanks frame the composition with architectural precision.

Powering reference 179178 is a movement from the Calibre 2130 family — Rolex's self-winding mechanical movement calibrated for the 26 mm Lady-Datejust case dimensions. The movement carries Rolex's Superlative Chronometer certification and is regulated to perform within ±2 seconds per day across five positions and two temperatures. The date disc, visible through the Cyclops magnifying lens, advances instantaneously at midnight — a mechanical refinement that requires careful engineering to achieve reliably at this scale.

The 18-carat yellow gold Lady-Datejust in reference 179178 occupies a specific and irreplaceable role in the Rolex matrix: it is simultaneously a dress watch and a jewellery object, wearable as everyday luxury or reserved for formal occasions. Pre-owned examples in excellent condition, particularly those accompanied by original box and papers, represent strong value relative to current retail pricing for comparable new configurations. For the collector or gift-giver seeking a watch of pure, uncomplicated elegance, reference 179178 is an exemplary choice.
