Rolex Explorer II
Designed in 1971, specifically for scientists exploring deep caverns, the Explorer II withstood extreme water pressure and diving. Considering very few people needed a watch for the rare occasion of diving below the Earth's surface, this piece became a contradiction for watch wearers everywhere. The Explorer II has held it's position as a leader of the Rolex sport line. This particular watch, coming from 2003, has few scratches and marks, leaving it in nearly perfect condition.
