Lady-Datejust 26 White Numerals Dial Smooth Bezel 18K Yellow Gold Steel Oyster 179163WRO

The Rolex Lady-Datejust 26 Ref. 179163 in the WRO configuration is a classically understated and highly legible timepiece from the previous 26 mm generation. This model utilizes the traditional two-tone blend known as Yellow Rolesor (the harmonious fusion of Oystersteel and 18K Yellow Gold). Setting it apart from the more common Fluted Bezel variants, this watch features a smooth, polished 18K Yellow Gold Smooth Bezel, which provides a sleek, modern, and simple silhouette that directs the viewer’s attention to the dial’s intricate details.

The centerpiece of this exquisite timepiece is the crisp White Dial . This bright, clean color provides superb visual contrast and a highly legible aesthetic. The dial is marked by traditionally styled, applied Roman Numerals (typically set in 18K Yellow Gold) for the hour markers. This choice of markers imparts a timeless, readable character, beautifully contrasting the pristine white field with the warm gleam of yellow gold.
