ROLEX OYSTER PERPETUAL 31MM (2013 B+P) #177200

The Rolex Midsize Oyster Perpetual boasts one of Rolex's most impressive features, the waterproof Oyster case.  Waterproof up to 330 feet, the case utilizes a process of screwing the stainless steel case back, Twinlock screw-down crown, and smooth bezel to the Monobloc middle case, creating an airtight seal.  Additionally, the Twinlock screw-down crown offers two sealed zones for double waterproofness.  Measuring 31mm, the midsize case is the perfect size for men or women.  Rolex pairs the 904L stainless steel construction with a contrasting blue dial set with Arabic and luminous hour markers and sweeping hands.  The Rolex Oyster Perpetual is offered at a reasonable price, making it an ideal introductory investment opportunity.
