Interestingly, the name Pearlmaster refers to the bracelet, not the dial. The Pearlmaster is constructed from closely woven chunks of 18-carat white or yellow gold or a combination of the two with pink gold called "Tridor," an abbreviation of the French term for "three golds" (trio d'or).
If you don't mind drawing attention to yourself, why not go for the white gold model with a sapphire-studded bezel encircling a white mother-of-pearl dial with diamond hour markers and a bracelet set with brilliants and sapphires?
Each Pearlmaster model has a date display, is self-winding, and is waterproof as far down as 300 feet (100 meters). I love the Roman numerals on the dial and how, at midnight, the Rolex calendar instantly jumps to the next date. Not the most exciting thing in the world, but it does serve as a simple sign of Rolex's precision engineering. This little beauty is not only waterproof but also built in what appears to be a miniature safe—it is literally manufactured from a solid block of gold. Rolex makes its own gold in its own foundry.
