Breitling Avenger B01 Chronograph GMT – Black Dial, 45mm

Built for pilots, explorers, and professionals who demand unwavering reliability, the Breitling Avenger Chronograph GMT 45 merges brute force with precision timing. This is a true tool watch: exceptionally robust, highly legible, and ready for action in the harshest environments. The bold 45mm stainless steel chassis houses a COSC-certified automatic chronograph movement, delivering both a precise second time zone and a professional-grade stopwatch in a single, purpose-driven package.

Why it stands out

• GMT/2nd Time Zone: The red GMT hand points to the 24-hour scale on the dial flange, letting you track a second time zone at a glance while the main hands keep local time. The hour hand can be advanced or synchronized without affecting the chronograph function, ideal for pilots crossing time zones.
• Professional chronograph: A central chronograph second hand with 1/4-second precision, plus a 30-minute counter at 12 o'clock and a 12-hour counter at 6 o'clock deliver timing for both short legs and long missions. A small seconds counter at 9 o'clock provides a steady running reference.
• COSC-certified accuracy: The Calibre 24 automatic chronograph movement guarantees dependable performance, beating at 28,800 vibrations per hour with 25 jewels and an approximate 42-hour power reserve.
• Glove-friendly controls: Rugged, grip-pattern crowns and chronograph pushers are designed for operation in cold or operational environments, even when you’re wearing gloves.
• Outstanding resilience: A solid 45mm stainless-steel case, anti-reflective sapphire crystal, and a unidirectional bezel combine to deliver durability, legibility, and reliability under pressure.

Its legibility in bright or low-light conditions, coupled with glove-friendly controls and high water resistance, makes it a reliable companion from cockpit to shore.

Practical use and care

• Use the GMT function to monitor home time while tracking mission time or other time zones during layovers and deployments.
• Rely on the unidirectional bezel for elapsed-time timing during activities like sailing or diving prep, with the crystal’s anti-reflective coating ensuring readability in direct sunlight.
• Protect the movement and seals by observing the 300m water resistance rating during shallow water activities and rain exposure; avoid extreme thermal shocks and strong shocks where possible.
• Choose the strap that best suits your environment: stainless steel for daily rugged use or a military leather strap for enhanced comfort in dry climates and flight decks.
