Rolex Datejust 179166

The Reference 179166 is a rare and exclusive model from the final 26mm Lady-Datejust generation (c. 2005-2015). The reference number specifies a case and President bracelet constructed entirely of solid 950 platinum (6), fitted with a smooth, domed bezel (6). The technical significance lies in the use of platinum, a material prized for its density, purity, and resistance to tarnish, which is significantly more challenging to machine than gold or steel. The watch houses the Caliber 2235 automatic movement. This reference is often distinguished by an ice-blue dial, a color treatment Rolex reserves almost exclusively for its platinum models. The combination of the understated smooth bezel with the noblest metal makes the 179166 a definitive “stealth wealth” timepiece, where value is expressed through material purity rather than overt decoration.
