Case Design

Measuring 31 mm in diameter, the Oyster case of this Datejust is both durable and elegant. Its monobloc middle case, crafted from corrosion-resistant Oystersteel, ensures exceptional resilience and a refined finish that maintains its luster through daily wear. The domed bezel in polished steel gives the watch a sleek, modern appearance, emphasizing the smooth curvature of the case and the meticulous craftsmanship that Rolex is renowned for.

Dial Legibility

The mint green dial of the Ref. 278240-0011 offers a pristine canvas of clarity and sophistication.
