The Rolex GMT-Master II reference 16713 represents a pivotal moment in horological history. This 40mm steel and gold two-tone sports watch, produced in 1991, exemplifies the model's evolution during its golden era. The iconic bi-directional rotatable bezel with 24-hour GMT function remains as functional today as when it left the manufacture, enabling simultaneous tracking of two time zones—a feature favored by pilots and global travelers. The robust Oyster case, paired with the prestigious Jubilee bracelet, strikes an elegant balance between professional capability and refined aesthetics. Powered by the reliable caliber 3185 automatic movement, this vintage timepiece combines enduring Swiss craftsmanship with the distinctive character that only decades of wear can impart. A collector's piece that transcends trend.
