Rolex Datejust 78243 Description

Reference 78243 is the engine-turned bezel model from the 31mm ‘Mid-Size’ Datejust 78xxx series, produced from approximately 1999 to 2006. This reference is historically significant as it was part of the generation that introduced the Rolex Caliber 2235. The technical specification ‘Yellow Rolesor’ (3) denotes a bi-metal construction, combining a 904L steel case with an 18k yellow gold winding crown and bracelet center links. The 24 in the reference specifies a finely engine-turned bezel in 18k yellow gold. It is fitted with a scratch-resistant sapphire crystal as standard.
