The Explorer II model, 1655, was introduced in 1971. The movement was either the 1570 or the 1575, and essentially this particular model was a GMT with a fixed stainless steel bezel. It had a distinctive dial with an extra hour hand that was designed specifically for speleologists, or cave explorers, who Rolex claimed, " soon lose all notion of time: morning, afternoon, day, or night." The extra hour hand, or 24 hour, would tell the explorers whether the 4 on the dial was 4:00 a.m. or 4:00 p.m. (16:00 hrs). 

This model has also been called the Steve McQueen Rolex. Steve McQueen may have worn a TAG Heuer Monaco wristwatch in the film Le Mans, but in real life he wore a Rolex Explorer II, model 1655. The Explorer II is very popular among collectors today.
