Rolex Explorer II ‘Freccione’ 1655 - Featured in Mondani’s ‘Rolex Explorer I, Explorer II, and Milgauss’ - ‘MK2’ Configuration

Rolex Explorer II 'Freccione' 1655 – Featured in Mondani's 'Rolex Explorer I, Explorer II, and Milgauss' – 'MK2' Configuration Introduced in 1971 as reference 1655, the Rolex Explorer II was never intended to replace the original Explorer, but rather to serve alongside it: as its more specialized, professionally focused sibling. Unlike its predecessor, which was a simple time-only watch, the Explorer II featured a practical day/night indicator, achieved through a fixed engraved bezel and the iconic orange 24-hour hand. This distinctive feature earned it the nickname 'Freccione' (Italian for 'big arrow'). Designed with cave explorers and adventurers in mind, this simple yet effective complication proved essential in environments devoid of natural light, marking a significant evolution in the Explorer family, shifting its focus from general exploration to more technical, professional applications. Visually, the 1655 is unmistakably a product of its era, featuring a bold and unconventional dial layout that sets it apart from all other Rolex sport models: a distinctive 24-hour format designed for use in conjunction with the fixed steel bezel and bright orange hand. Discontinued in 1985, the reference 1655 remains a grail for collectors. Its daring design, historical relevance, and utilitarian spirit have cemented its status as one of the most iconic and distinctive Rolex tool watches ever produced. The present example, dating to 1974, is an exceptional specimen of this legendary reference. Its significance is further heightened by its inclusion in the definitive reference book reference Rolex Explorer I, Explorer II, and Milgauss, published by the internationally acclaimed and historic Guido Mondani Editore: an accolade that underscores the watch's provenance and collector value. Furthermore this model is a textbook representation of the second series, featuring the very sought-after 'MK2' black matte dial and the matching 'MK2' engraved 24-hour bezel. It is currently fitted with a folded link Oyster bracelet 7836, complete with 380 endlinks and the correct no-date clasp. Every detail aligns perfectly with what one expects from a 3.7 million serial number 1665, affirming its authenticity and desirability. Despite its age, the watch remains well-preserved, with strong case bevels and a robust bezel, exemplifying the enduring quality and character of this legendary tool watch. Its prestigious, publication-worthy provenance and exceptional correctness significantly elevate the watch's status, cementing it as a standout example of an already highly sought-after reference: a true collector-grade piece in every sense.
