Rolex Datejust 31 Yellow Rolesor — Olive Green Diamond Dial | Ref. 278243

The 278243 brings the current-generation Datejust 31 into the Rolesor category with one of the more distinctive dial colour choices available in the lineup: olive green. As a member of the 278xxx reference family introduced in recent years, this watch benefits from the updated 31 mm Oyster case architecture and the contemporary Calibre 2236, placing it firmly in Rolex's modern production era while retaining the timeless two-tone Rolesor aesthetic that has distinguished this collection since the 1940s.

Calibre 2236 is a self-winding manufacture movement developed specifically for Rolex's 31 mm women's watches, incorporating a Syloxi hairspring — a silicon component offering thermal stability and magnetic resistance without the need for a paramagnetic alloy. The case pairs Oystersteel and 18ct yellow gold, with gold applied to the bezel and crown, and the Jubilee bracelet echoing this material split across its five-piece links. The olive green diamond dial features diamond hour markers, lending it a jewel-set richness that elevates it beyond the standard index configurations.

Olive green dials are relatively recent additions to Rolex's palette and have proven extremely popular across the entire Datejust range, reflecting a broader market appetite for earthy, nature-inspired tones in fine watchmaking. The 278243 in this configuration — yellow Rolesor with diamond dial — appeals directly to buyers seeking a watch that bridges the gap between luxury dress piece and modern fashion statement. Strong demand for green-dial Rolex references across the board lends this specific variant meaningful collector and resale appeal.
