Rolex Explorer II 1655

Rolex Explorer II Reference 1655 is a landmark tool watch that embodies Rolex’s commitment to functional design and professional utility. Launched in 1971, the 1655 was engineered specifically for cave explorers, polar researchers, and adventurers operating in environments where distinguishing day from night was critical. Unlike modern GMT watches, the 1655 features a fixed stainless-steel bezel engraved with a 24-hour scale, paired with an oversized bright orange 24-hour hand nicknamed “Freccione” (Italian for “arrow”). This hand makes one full rotation every 24 hours, allowing the wearer to instantly determine AM/PM orientation rather than track a second time zone.
