Explorer 216571 replica

A watch designed for deep-sea diving, the Rolex Deepsea is waterproof to a depth of 3,900 metres (12,800 feet). The Oyster’s case has been redesigned to ensure that the size and thickness of the watch are not compromised by its amazing resistance to pressure. For this reason, the brand invented the Ringlock system. The case structure of Rolex’s patented Ringlock system allows the Rolex Deepsea to withstand huge deep water pressures.
