The Chronomat Automatic GMT 40 is Breitling's tribute to travel, not only for its dual time zone display, but also because of its easy going aesthetics. Subtle dial colors, combined with an all-steel case and bracelet, work with any wardrobe. Meanwhile, the tone-on-tone 24-hour scale lets the red GMT hand speak for itself. The Breitling Caliber 32 powers the GMT complication. Its 24-hour scale lets the user track a second time zone and know at a glance whether its day or night, while the "onion" crown (a classic Chronomat feature named for its fluted-dome shape) allows for easy adjustments. As an all-purpose sports watch, meant to cross over between Breitling's air, land, and sea universes, the GMT 40 has an impressive 200m water resistance. Known as "a watch for every pursuit," the Chronomat mission is truer now than ever because of the GMT 40's practical size and understated style. Sturdy enough for the gym, yet smart enough for black tie: If there's one watch to travel with, this is it.
