Rolex Datejust 26 Yellow Gold — Black Diamond Dial, Fluted Bezel | Ref. 179238

Reference 179238 brings the Datejust into its 26mm configuration — historically the entry point of the ladies' Datejust family — executed entirely in 18ct yellow gold. The black dial set with diamond hour markers creates a composition of high contrast and formality: the deep ebony ground absorbs light while the diamonds and polished gold surround it with maximum luminosity. The fluted bezel in matching yellow gold is among the most historically resonant elements of the Datejust design language, originating with the model's 1945 introduction and unchanged in its essential geometry since.

Calibre 2235 is the movement designated for the 26mm Datejust, a self-winding manufacture calibre developed by Rolex for its smaller case diameters. It incorporates a Parachrom hairspring for magnetic and shock resistance, alongside Paraflex shock-absorber elements, delivering a 48-hour power reserve within a movement architecture refined to fit the constraints of the 26mm Oyster case. The solid 18ct yellow gold case and bracelet provide both precious-metal integrity and the 100-metre water resistance guaranteed by the Twinlock crown system.

The 26mm Datejust in full yellow gold with a black diamond dial occupies a specific niche in the collector landscape — one that prizes classical proportions, precious-metal authenticity, and the formal visual language of the mid-century dress watch. These smaller Datejust references have attracted renewed interest as micro-watch trends have elevated appreciation for sub-30mm cases. Reference 179238 in this configuration represents a fully realised example of Rolex's precious-metal craft applied to its most intimate scale.
