Collectors prioritize this reference for its technical complexity, specifically the 24-second tourbillon inclined at 25 degrees and the rotating titanium globe that provides a visual representation of world time. The 43.5mm case utilizes an asymmetrical lateral window to display the globe from a profile view. On the secondary market, this white gold reference typically trades in the mid-to-high six-figure range, often between $300,000 and $450,000 depending on condition and provenance. A notable production detail is the limited nature of these pieces; while not a numbered limited edition in white gold, total annual output for the entire GMT line remained extremely low, often fewer than 100 units across all metals.", "score": 199}]}
