The Explorer, launched in 1953, sets itself apart with a simple design and a highly legible black dial with characteristic 3, 6 and 9 numerals and large index hour markers. It is a tool watch, created to tell time accurately, whatever the circumstances. Even in the dark, the dial is easy to read, thanks to the Chromalight display. Today, the Explorer is available in a 36 mm diameter – the size of the 1953 original model – as well as in a 40 mm diameter.

The Explorer II was introduced in 1971 and, in the same spirit as the Explorer, perpetuates the privileged relationship Rolex enjoys with exploration. Thanks to its 24-hour display comprising an additional, orange hour hand and an engraved bezel, the Explorer II allows the wearer to clearly distinguish daytime from night-time hours – a practical option in places where distinguishing day from night is difficult, such as at the poles at certain times of the year, and in caves – or to read the time in a second time zone.

Like all Rolex watches, the Explorer and Explorer II are covered by the Superlative Chronometer certification. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories, according to its own criteria. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
