Among the most distinctive and charismatic Rolex sports watches ever produced, the Explorer II reference 1655 was conceived for explorers operating beyond the reach of natural daylight. Its legendary orange 24-hour hand, earning the nickname “Freccione” among collectors, has become one of the defining signatures of vintage Rolex tool watches.

The present example bears a serial number in the 5.1 million range, fully consistent with production during the late 1970s and the highly desirable Mk II dial configuration found on period examples. The beautifully preserved black dial displays crisp printing, attractive tritium lume and outstanding visual balance, contrasted by the vivid orange 24-hour hand and engraved steel bezel.
