Rolex Explorer II ‘Freccione’ 1655 - ‘Albino’ - ‘MK2’ Matte Black Dial

Launched in 1971 under reference Rolex Explorer II 1655, the Rolex Explorer II was developed as a purpose-built tool watch designed to complement—rather than replace—the original Explorer. Conceived for use in extreme conditions, it was specifically tailored to meet the demands of professionals operating in environments devoid of natural light. Unlike its simpler counterpart, the Explorer II introduced a practical and highly legible solution: a fixed 24-hour engraved bezel paired with a bold orange 24-hour hand, allowing the wearer to clearly distinguish between day and night. This striking feature would later earn the model its well-known Italian nickname, “Freccione.” Bold in both purpose and execution, the reference 1655 perfectly reflects the experimental design language of the 1970s. Its dial layout is unique within the Rolex sports collection, prioritising legibility while embracing a distinctly technical aesthetic. At its core lies the reliable Calibre 1570, a movement renowned for its durability and precision, housed within a robust 40 mm stainless steel Oyster case featuring strong proportions and a utilitarian brushed finish that underscores its tool-watch character. The present example, dating to 1974, represents an early phase of production and is fitted with an ‘MK2’ matte black dial alongside a corresponding ‘MK2’ fixed 24-hour bezel—details that mark an important stage in the evolution of the reference and are particularly appreciated by collectors for their balance and period correctness. Of special note is the signature orange 24-hour hand, which over time has developed a softer, pale hue, a natural ageing process often referred to by collectors as the “Albino” effect. Unconventional, highly functional, and unmistakable in appearance, the Explorer II ref. 1655 occupies a unique position within the Rolex sports catalogue, both for its design and its historical relevance. Preserved in excellent condition, this 1974 example embodies the spirit of the model’s early years and represents a compelling opportunity for collectors seeking an iconic and characterful vintage tool watch.
