The Tropic strap is a renowned watch strap originally crafted in the 1960s, primarily for dive watches. Made from vulcanized natural rubber, it is celebrated for its durability, water resistance, and comfort, making it ideal for underwater use. The strap's design is characterized by a distinctive crisscross pattern, which provides both aesthetic appeal and functional grip. Historically, it was the official strap for iconic dive watches like the Rolex Submariner and Blancpain Fifty Fathoms, and it remains a popular choice among vintage watch enthusiasts. Its ability to resist odors and maintain its form under water further enhances its suitability for diving. Unlike modern silicone straps, the Tropic strap retains a lustrous sheen and a thin profile, offering a blend of elegance and robustness. This combination of features makes it versatile, suitable for both sports and casual wear, and compatible with a variety of watch models, from classic divers to contemporary chronographs.
