Rolex Women’s Datejust 28mm Datejust. 1. The Oyster-style case of the ladies’ log-type is a model of sturdiness, elegance and perfect proportions. 316L stainless steel is used to forge the stainless steel watch case with high corrosion resistance. This superalloy is not only very durable and easy to polish, but its beauty remains undiminished even in the most extreme environments. 2. The built-in and original imported NH05 movement is extremely stable. Its anti-vibration and geometric structure enable the movement to maintain regular operation at any position. 3. The triangular hole pattern bottom cover is tightened with a special tool to completely seal the case. The winding crown adopts a double-lock double waterproof system, which is firmly screwed on the case to make it more waterproof. 4. The mirror surface is made of scratch-resistant blue crystal, with a small convex lens at 3 o’clock for easy reading of the date. The women’s log-type waterproof Oyster case gives the best protection to the high-precision movement. 5. The new concealed connection method under the watch strap and outer ring ensures a seamless visual effect between the strap and the case. The redesigned commemorative strap is equipped with a new generation of concealed crown buckle, which opens with a hinged Rolex crown logo. The Oyster strap style is equipped with a folding Oyster buckle. Rolex classic ladies’ watches have always been synonymous with elegant style and precise timepieces, condensing the elegance and unique functions of the log type into a small and exquisite case, which is more suitable for women’s slender wrists.
