When the first waterproof oyster watch was created in 1926, it spawned the Replica Rolex Oyster Perpetual Watch line. One of Replica Rolex’s most popular models is the oyster. They include all the features of the Oyster Perpetual series, including precise timekeeping, a water-resistant oyster watch casing, and a swing-through automated chain movement that never stops. When it comes to clocks and timepieces, this new model has it all. The dial is crystal clear and simple to read thanks to the latest generation of oyster-type constant motion blue crystal mirror on the rear of the anti- reflective coating.
