The Rolex Lady-Datejust reference 179173 is one of the most popular classic women’s models from Rolex. It features a refined 26mm Oyster case in Yellow Rolesor (Oystersteel and 18k yellow gold), paired with a distinctive fluted 18k yellow gold bezel. Powered by the in-house Calibre 2235 automatic movement, it offers approximately 48 hours of power reserve and Superlative Chronometer precision. Available in a wide range of dial options including champagne, silver, white, black, mother-of-pearl, and diamond-set versions. Typically fitted with the elegant two-tone Jubilee bracelet and featuring the iconic Cyclops lens over the date. Water-resistant to 100 metres, it is a versatile and timeless choice for both everyday wear and formal occasions. (This 26mm size was discontinued around 2015/2016 when Rolex introduced the larger 28mm Lady-Datejust).
