With its unique ability to track two time zones simultaneously, the GMT watch has been a collector’s favorite since its introduction in the 1950s. The Mirabel reimagines this complication—typically found in sportier designs—and brings it into the realm of classic dress watches. The result? A GMT timepiece like no other—or, if you will, a dress watch with a party trick.
