The Explorer is emblematic of the privileged relationship that has always bound Rolex and exploration. A pioneering spirit prompted Rolex, in the 1930s, to equip numerous Himalayan expeditions with watches. Their observations had a direct impact on the development of the Oyster and the quest for greater precision, robustness and reliability.


The Explorer’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness. Its characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. Fitted with the Twinlock double waterproofness system, the winding crown screws down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Explorer’s high-precision movement.
