Rolex Datejust 69178

Reference 69178 is the archetypal solid gold model from the 26mm Lady-Datejust 69xxx series, produced from approximately 1983 to 1999. The watch is powered by the Rolex Caliber 2135, historically significant as the first Rolex ladies’ movement to achieve COSC chronometer certification. The technical specification denotes a 26mm Oyster case and President bracelet constructed from solid 18k yellow gold (8), fitted with a classic fluted bezel (17 configuration code). A key technical variant within its production is the crystal material: early models used acrylic, while later examples from the mid-1990s onward were upgraded to a scratch-resistant sapphire crystal.
