Rolex Datejust 78240

Reference 78240 is the all-stainless steel, engine-turned bezel model from the 31mm ‘Mid-Size’ Datejust 78xxx series, produced from approximately 1999 to 2006. Its primary technical feature, specified by the 24 in the reference number, is a ‘finely engine-turned’ bezel crafted from stainless steel. This reference is historically significant as the successor to the Ref. 68240, featuring the upgraded Rolex Caliber 2235 and a scratch-resistant sapphire crystal as standard. It is a key ‘end-of-an-era’ reference as it represents one of the final applications of the now-discontinued engine-turned bezel.
