Rolex Datejust 178239 Description
Reference 178239 is the solid 18k white gold, fluted-bezel model from the 31mm ‘Mid-Size’ Datejust 178xxx series, produced from c. 2006 into the late 2010s. It is powered by the Rolex Caliber 2235. Its technical specification denotes a 31mm case with a fluted bezel (23 code) in 18k white gold (9 suffix) and is fitted with a sapphire crystal. It is built on the modern, heavier case platform with fully polished lugs and a solid-link President bracelet. Its significance lies in its role as the discreet, precious metal flagship of the 31mm line, combining the classic fluted bezel with the understated look of white gold.
