This vintage Rolex Explorer II “Freccione” MK2 Ref. 1655 is a legendary 1970s tool-watch that blends rugged functionality with unmistakable vintage character. Housed in a robust stainless steel case of 40 mm diameter, it features a fixed 24-hour steel bezel and a domed plexiglass crystal — design choices born from its original purpose: aiding spelunkers and adventurers spending long periods underground or in polar regions. The dial is a matte black “frog-foot” MK2, recognizable by its stylized Rolex coronet, tritium-filled hour markers and hands, and the signature large orange 24-hour “big arrow” hand, nicknamed “Freccione.” Inside, the watch houses the reliable automatic Caliber 1575, inheriting the precision and endurance of its era — ideally suited to both extreme environments and everyday wear. It is mounted on a correct vintage Oyster bracelet (78360/580 end-links), which completes the toolish, utilitarian vibe while ensuring a comfortable and secure fit. With its bold design, historical purpose, and unmistakable vintage DNA, the Explorer II 1655 “Freccione” remains one of the most iconic and sought-after vintage Rolex watches — a timepiece built for extremes yet timeless in style.
