Rolex Datejust 179178

The Reference 179178 denotes the archetypal solid gold ladies’ watch from the final 26mm Lady-Datejust generation (c. 2005-2015). The technical specification is a 26mm case constructed of solid 18k yellow gold (8) with a classic fluted bezel (7). This reference succeeded the 79178, carrying over the iconic design but implementing the technical upgrades of the six-digit series. These improvements include a more substantial case with broader, high-polish lugs and the use of solid-link 18k gold President or Oyster bracelets with improved clasp mechanisms. It is powered by the Rolex Caliber 2235, a COSC-certified automatic movement. Its historical significance is as the modern flagship of the core Lady-Datejust line.
