Rolex Datejust 178275

Reference 178275 is the solid 18k Everose gold, fluted-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 27 code specifies the classic fluted 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, iconic configuration for the modern 31mm Datejust in Rolex’s patented pink gold alloy.
