Rolex Datejust Yellow Rolesor — Olive Green Diamond Dial | Ref. 278343

The Datejust 31 in Yellow Rolesor occupies a distinct position within Rolex's mid-size offering — large enough for confident wear yet refined enough for the most formal occasions. Reference 278343 pairs the warm lustre of 18ct yellow gold with the cool practicality of Oystersteel, a combination that defines the Rolesor aesthetic Rolex pioneered decades ago. The domed diamond bezel lifts this configuration beyond the everyday, while the olive green diamond dial introduces an unexpected earthiness that makes the piece genuinely distinctive.

Calibre 2236 drives this reference, a movement developed specifically for Rolex's 31 mm ladies' range. It incorporates the Syloxi silicon hairspring for superior resistance to temperature variation and magnetic fields, and it carries a 55-hour power reserve. The dial itself is set entirely with brilliant-cut diamonds in place of conventional hour markers, and the olive green lacquer beneath them offers unusual depth and tonal complexity compared to the more common champagne or white variants.

This is a watch that appeals to collectors who want something beyond the standard Datejust palette. The olive green and diamond combination is limited in production relative to the classic dial options, making it a more considered purchase. Yellow Rolesor with a diamond bezel commands a firm premium on the secondary market, and condition of the bezel setting is the first thing to verify when buying pre-owned. Suited to someone who dresses with intention and wants jewellery-level presence on the wrist without sacrificing a true Rolex movement.
