Rolex Explorer I

The Explorer launched in 1953, the same year as the Submariner. Where the Submariner went underwater, the Explorer went upward — born from Rolex's association with Himalayan mountaineering and the 1953 Everest expedition. Its defining features are the 3-6-9 Arabic numeral dial, Mercedes hands, and a no-complications approach to legibility in adverse conditions.

Pre-Explorer and early references (1952–1959)
