Rolex Datejust Yellow Gold — Fluted Bezel Mother-of-Pearl Roman Dial | Ref. 179178

Crafted entirely in 18 ct yellow gold, the Lady-Datejust 26 reference 179178 belongs to a tradition of Rolex dress watchmaking that stretches back to the introduction of the Datejust in 1945. At 26 mm, the case diameter is intimate and precise, its Oyster architecture — monobloc middle, screw-down case back, and Twinlock winding crown — providing 100 metres of water resistance without compromising the watch's refinement. The fluted bezel, machined from solid gold and polished to a mirror finish, introduces the vertical striations that are among the most enduring motifs in Rolex's visual language, originally introduced to serve a functional purpose as a means of tightening the bezel against the case.

The mother-of-pearl dial is the centrepiece of this reference's appeal. Harvested from mollusc shells and hand-polished to reveal its natural iridescence, each mother-of-pearl panel is unique, ensuring that no two examples of 179178 are identical at the dial level. Roman numeral hour markers applied in yellow gold complement the warm palette of the case and bracelet, while the date aperture at three o'clock maintains the Datejust's practical identity. The President bracelet — Rolex's three-piece-link creation first introduced in 1956 — completes the ensemble with its semi-circular links and concealed folding clasp.

At the heart of the watch beats the calibre 2235, a self-winding movement with a Parachrom hairspring and Paraflex shock absorbers that deliver resilience belying the watch's delicate appearance. The 179178 is a heirloom-grade proposition: technically sound, aesthetically enduring, and suffused with the particular warmth that only a monometallic gold construction can convey.
