Rolex Datejust 178245

Reference 178245 is the solid 18k Everose gold, smooth-bezel model from the 31mm ‘Mid-Size’ Datejust 178xxx series, produced from c. 2006 into the late 2010s. The key technical feature is the material: Everose gold (5) is Rolex’s proprietary pink gold alloy containing platinum for long-term color stability. The 24 code specifies the smooth, domed bezel. It is powered by the Rolex Caliber 2235 and features the updated heavier case and solid-link President bracelet. Its significance is as the primary understated configuration for the modern 31mm Datejust in Rolex’s patented pink gold alloy.
