A warm take on the travel watch that defined the format, the Rolex GMT-Master II ref. 16718 brings the line's dual-time utility into a full 18K yellow gold case. Here, the black dial keeps the look crisp and purposeful, giving this 40mm configuration the direct, legible character collectors want from a GMT-Master II. Its automatic movement pairs GMT functionality with a date display. At 12mm thick, it wears with the compact, balanced proportions that make this reference so enduring.
