Breitling Chronomat GMT 40 Automatic Black Dial Silver Steel Watch

The Chronomat GMT 40 is Breitling’s dedicated travel companion: a versatile, dual time zone watch that pairs a refined black dial with a durable silver steel case and bracelet. Its understated, tone-on-tone 24-hour scale makes the red GMT hand pop with purpose, so you can read your second time zone at a glance—day or night—without squinting at the dial.

Powered by the Breitling Caliber 32, this self-winding mechanical movement drives the GMT complication with a full second time zone display. The 24-hour scale helps you distinguish day from night across zones, while the iconic onion crown ensures smooth adjustments even after long flights. With a robust 200-meter water resistance, it’s as comfortable on a dive trip as it is in a business meeting or a weekend getaway.

What makes it stand out

• Dual time zone in a single glance: track two zones with a dedicated 24-hour scale and a bold red GMT hand.
• All-steel, versatile design: a rugged yet refined aesthetic that transitions from gym to black-tie events.
• Onion crown for easy handling: a Chronomat signature that combines tactile feedback with classic style.
• 200m water resistance: built to handle rain, splashes, swimming, and snorkeling with confidence.
• High-contrast readability: cambered sapphire crystal glare-proofed on both sides keeps the dial legible in all conditions.

Who it’s for

Ideal for professionals who travel frequently, digital nomads who juggle meetings across time zones, and watch enthusiasts who value a sport-luxury look with practical functionality. It’s equally at home with a tailored suit, workout gear, or weekend casual.

Why it solves real problems

Rather than juggling multiple watches or relying on mental math for time zones, the Chronomat GMT 40 gives you a reliable, easy-to-read second time zone right on your wrist. The robust build and water resistance prevent hesitation in daily life—whether you’re flying, swimming, or navigating a busy itinerary. The 40mm case size balances wrist presence with comfort, ensuring it doesn’t overwhelm, whether you’re at the office or on a flight deck.
