Rolex Datejust Yellow Gold — Mother-of-Pearl Diamond Dial | Ref. 279178

A second iteration of reference 279178 demonstrates the breadth achievable within a single model number through dial and gemstone variation. Where the silver-Roman configuration pursues formal restraint, this Mother-of-Pearl Diamond variant redirects the 28 mm yellow-gold Lady-Datejust toward high jewellery territory: the iridescent mother-of-pearl base creates a living, organic backdrop whose natural lustre shifts from cream to pale rose under varying light, while diamond hour markers introduce controlled brilliance at each index position.

The fluted yellow-gold bezel ties the case surround to the bracelet's outer links, maintaining visual coherence across all three components. Inside, the Calibre 2236 drives both timekeeping and date functions with the precision expected of a COSC-certified manufacture movement. Its Syloxi silicon hairspring — produced using a lithographic etching process adapted from microelectronics manufacturing — eliminates the positional errors associated with conventional metallic springs and requires no lubrication at the escapement, reducing long-term service requirements.

The President bracelet in 18 ct yellow gold is an exclusive attribute of the Day-Date and premium Lady-Datejust configurations, its semi-circular three-piece links providing exceptional conformity to the wrist contour. The concealed Crownclasp preserves the bracelet's uninterrupted aesthetic while providing a secure double safety system. For those who collect Rolex along the axis of gem-set dial artistry, this variant of the 279178 offers a compelling study in natural material and precious stone in dialogue.
