The Replica Rolex Explorer II Watches, initially available only in black, was created to satisfy cave explorers who were often active in the dark and could not tell day from night. This explains the clear orange fourth hand combined with the 24-hour outer ring that informs of morning and afternoon. This design was nicknamed “freccione”, meaning big arrow, by Italian collectors in the 1990s. It has to be admitted that this watch had a very narrow audience. When the Rolex Explorer II Replica Watches was first released in 1971, it was natural to think that Rolex should at least take other professional explorers into account and let them benefit from this design as well.
