The Chronomat Automatic GMT 40 is Breitling's tribute to travel, not only for its dual time zone display, but also because of its easygoing aesthetics. A subtle black dial, 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 it's 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 200 m water resistance.
