1655 Rolex

Originally introduced in 1954, the Rolex 1655, nicknamed the Explorer II, was designed for spelunkers who needed to keep track of day and night underground, which is honestly so specific but also kind of amazing. It’s got this distinctive 24-hour orange hand that, fun fact, eventually faded into a softer shade—super sought after now. At Tropical Watch, finding these historic gems feels a little like treasure hunting, minus needing a cave.
