Some of the common features shared by ladies' Rolex watches include being set with a synthetic sapphire crystal, which guards the dial from scratches, dust build-ups, water intrusion, and external pressure. A hermetically sealed caseback renders most of the Rolex timepieces -- especially those belonging to the Rolex Oyster Perpetual line -- a depth rating of 330 feet. Some watches in the Rolex Oyster Perpetual Professional line offer an ever greater depth rating, such as the Rolex Submariner, which can go as deep into the sea as 1,000 feet, or the Rolex Deepsea, which has a depth rating of 12,800 feet. Most importantly, all Rolex Oyster Perpetual and Rolex Oyster Perpetual Professional watches are marked with a "Superlative Chronometer" certification from the Contrôle Officiel Suisse des Chronomètres, or COSC. This certification ensures accurate timekeeping and reliable performance, even if the ladies' Rolex watches are exposed to extreme changes in environmental conditions.
The Rolex Cellini, a collection of "dress watches", offers several models designed for women as well, namely the Rolex Cellini Danaos, the Rolex Cellini Celissima, and the Rolex Cellini Orchid. These watches are notable for their highly accurate quartz movements and intricately crafted designs.
