Rolex Datejust 69166

Reference 69166 is an exceptionally rare flagship model from the 26mm Lady-Datejust 69xxx series, produced from approximately 1983 to 1999. Its technical specification denotes a 26mm Oyster case and President bracelet constructed from solid 950 platinum (6), fitted with a smooth, domed bezel (16 configuration code). The watch is powered by the Rolex Caliber 2135, historically significant as the first Rolex ladies’ caliber to achieve COSC chronometer certification. A key technical variant is the crystal, which transitioned from acrylic to sapphire in the mid-1990s. The significance of the Ref. 69166 lies in its status as the ultimate ‘stealth wealth’ timepiece of its generation.
