The Rolex Explorer II originated in 1971 as reference 1655. The Explorer II was equipped with an orange hand to be used as a daylight indicator for those who professionally didn’t see daylight for a longer period of time.
In 1974 minor changes were applied to the Explorer II, such as the second’s hand receiving an additional luminous dot. For the consecutive year 1975, Rolex surprisingly decided to use red instead of orange paint for the 24-hour hand.
