The Rolex GMT-Master is a luxury sports watch originally designed in the 1950s for international pilots. Known for its distinctive dual-time zone functionality, the watch features a 24-hour rotating bezel and an additional GMT hand, allowing wearers to track two time zones simultaneously. With its robust Oyster case, iconic color schemes (like the “Pepsi” red-and-blue bezel), and automatic movement, the GMT-Master and its successor, the GMT-Master II, have become highly sought-after for both their practicality and timeless style.
