EXPLORER II 216570
Oyster, 42 mm, steel
Extreme environments, such as the polar regions, have always been real-life proving grounds for Oyster watches. The Explorer II is natural heir to the Explorer as a reliable guide, a tool and a companion for explorers, speleologists and vulcanologists. When it was launched in 1971, the Explorer II set new standards for chronometric precision, strength, autonomy and clarity. It features a distinctive 24-hour hand, an invaluable aid to distinguish daytime hours from night around the poles and beneath ground.
3187 MOVEMENT
Features
The Explorer II is equipped with calibre 3187, a self-winding mechanical movement entirely developed and manufactured by Rolex. In addition to the conventional hour, minute and seconds hands, it features a 24-hour hand to display a second time zone. The 3187 is fitted with a Parachrom hairspring and Paraflex shock absorbers, offering greater resistance to shocks and to extreme conditions.
