Rolex GMT-Master

The original GMT-Master before the GMT-Master II, with a 24-hour hand linked to the rotating bezel for reading a second timezone. Spanning gilt and matte dials with Pepsi (red and blue) and black bezels, these are travel-era grails. Authentication centers on the correct caliber for the reference and era, correct dial generation, period-correct bezel insert, crown-guard profile where relevant, and overall originality. Service dials, swapped inserts, and frankenwatches are the dominant vintage risk.
