Introduced in 1971 and produced for more than a decade, the reference 1655 was conceived as a true purpose-built tool watch for spelunkers and cave explorers. Operating for prolonged periods without natural light, these professionals required a clear and immediate distinction between day and night. Rolex addressed this need with a fixed 24-hour bezel and a bold, high-visibility orange hand—an intuitive, function-first solution that perfectly embodies the brand’s utilitarian design ethos of the era.

Often nicknamed the “Orange Hand,” or Freccione (Italian for “big arrow”), the 1655 is among the most distinctive and charismatic models to emerge from Rolex’s professional lineup of the 1970s. Its oversized orange 24-hour hand gives the watch an unmistakable visual identity—instantly recognizable and impossible to confuse with any other reference. This singular design language has firmly established the 1655 as a cult favorite among seasoned collectors.

This example is a Mk4 variant, fresh to market and a strong representation of the esoteric Orange Hand Explorer II. Showing honest, moderate wear, the thick 6.2 million-serial case remains unpolished and well-defined. The vivid orange hand stands out beautifully against the black dial, complemented by rich, honey-toned tritium luminous.

Powering the watch is its original Caliber 1570 movement, paired with a Rolex 78360 bracelet with 580 end links and a VF clasp code dating to 1981. Altogether, this is a vibrant, honest, and highly wearable Explorer II—one that can be enjoyed regularly while showcasing one of the most iconic design expressions of 1970s Rolex.
