Rolex Datejust 68273

Reference 68273 is the archetypal Yellow Rolesor model from the 31mm ‘Mid-Size’ Datejust 68xxx series, produced from the early 1980s to the late 1990s. It is powered by the Rolex Caliber 2135, historically significant as the first Rolex ladies’ (and mid-size) caliber to achieve COSC chronometer certification. The technical specification ‘Yellow Rolesor’ (3) denotes a bi-metal construction, combining a stainless steel case with a solid 18k yellow gold fluted bezel (27 code). A key technical variant is the crystal, which transitioned from acrylic to sapphire in the later years of production.
