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).
The watch initially when it was first marketed, the second hand was straight and
the extra hour hand was a bright orange. In 1974 a luminous circle was added
and models manufactured after 1975 the extra hour hand was painted a bright
red. The production of the 1655 continued until 1985 when it was discontinued.
A debate exists in regard to when the orange hand was no longer used on the
dial. Reference texts seem to agree that the orange hand was discontinued by
the mid 70's. It is interesting to note that many 1655's made after the mid
70's and into the 80's have orange 24 hour hands. Perhaps the explanation is
that the red hands faded to orange, just as orange hands have been known to fade
The Explorer 11 was not a popular watch during its production run from 1971 to
1985. The dial is cluttered and even considered illegible by some watch
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.
