Rolex Explorer II ‘Freccione’ 1655 - ‘MK4’ Matte Black Dial - Original Warranty

Introduced in 1971 as reference 1655, the Rolex Explorer II was conceived not as a replacement for the original Explorer, but as a more specialised companion within the same family: a watch designed for professionals operating in extreme environments. While the classic Explorer remained a straightforward time-only instrument, the Explorer II brought a functional innovation: a fixed engraved 24-hour bezel paired with a highly visible orange 24-hour hand. This distinctive feature allowed the wearer to differentiate between day and night, a crucial function for cave explorers and adventurers working in places where natural light is absent. The bold orange hand quickly earned the model its famous nickname, “Freccione”; Italian for “big arrow”.

Purpose-built yet visually striking, the Explorer II ref. 1655 reflects the daring design language of the 1970s. Its dial layout is unlike any other Rolex sports watch of the era, combining legibility with a uniquely technical aesthetic. Powering the watch is the dependable Rolex Caliber 1570, ensuring robustness and precision. The movement is housed within a 40 mm stainless steel Oyster case with thick lugs and a fully brushed finish, reinforcing the watch’s tool-watch identity and rugged character.

The present specimen, preserved in overall excellent condition and accompanied by its original warranty, features the ‘MK4’ dial layout alongside a corresponding ‘MK3’ 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.

Distinctive, unconventional, and entirely purpose-driven, the Explorer II ref. 1655 stands apart within the Rolex sports catalogue: both in design and historical significance. With its unmistakable “Freccione” hand and pioneering functionality, it remains one of the most iconic vintage tool watches ever produced. Preserved in excellent condition, this 1980 example is accompanied by its Original Puncher Warranty (damaged) and is now offered to the highest bidder.
