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

Reference 179178 represents the Lady-Datejust in full 18ct yellow gold — a solidly precious-metal specification that elevates the 26mm Oyster case into the realm of fine jewellery. The silver dial is set with diamond hour markers that catch the light with quiet intensity, their individual scintillation contrasting with the disciplined symmetry of the fluted bezel. Rolex's fluted bezel design is one of the marque's most enduring signatures, its 44 stepped facets machined to exacting tolerances before receiving a high polish that remains crisp indefinitely.

The movement powering this reference is Rolex's Calibre 2235, a self-winding micro-rotor calibre engineered exclusively for the smaller Datejust case families. Running at 28,800vph with a bidirectional rotor and Parachrom hairspring, it achieves a certified accuracy of -2/+2 seconds per day. The Oyster case, fully rendered in 18ct yellow gold, provides water resistance to 100 metres — a specification that underscores Rolex's insistence that even their most jewel-set pieces remain genuine tool watches at heart.

The 179178 in yellow gold with a silver diamond dial and fluted bezel is one of the purest expressions of the Lady-Datejust's heritage. The fluted bezel in yellow gold — visually indistinguishable at a glance from the iconic President bracelet in the same material — creates a unified, entirely precious-metal aesthetic that has endured since the reference's introduction. For collectors of classic Rolex precious-metal pieces, this configuration is as canonical as the Day-Date in yellow gold: a timepiece that needs no embellishment beyond the materials themselves.
