Rolex Datejust 178158

Reference 178158 is a factory gem-set model from the 31mm ‘Mid-Size’ Datejust 178xxx series, produced from c. 2006 into the late 2010s. Its technical specification denotes a case constructed from 18k yellow gold (8) with the unique 15 configuration code. This code specifies a bezel factory-set with 24 brilliant-cut diamonds, paired with a dial featuring a large, diamond-paved Roman numeral “VI”. This reference is significant for its coordinated gem-setting across both the bezel and dial on the modern, heavier 31mm case platform, representing a distinctively artistic factory design. It is powered by the Caliber 2235.
