The Breitling Super AVI B04 Chronograph GMT 46 Mosquito, reference YB04451A1B1X1, is a remarkable fusion of cutting-edge chronometric technology and historic tribute. Inspired by the iconic de Havilland Mosquito aircraft of World War II—an aircraft known for its all-wood airframe and incredible versatility—this timepiece captures the daring spirit and innovation of aviation pioneers.

Design Rooted in Aviation Legacy

Featuring a bold 46mm black ceramic bezel paired with a stainless steel case, this watch delivers a commanding presence on the wrist. The black dial is accentuated by large white Arabic numerals for clear legibility, while the red GMT hand and chronograph details inject a sporty, high-performance flair. The vintage-inspired brown calfskin leather strap with contrast stitching mirrors classic pilot gear, enhancing its retro aviation appeal.

Caliber B04: In-House Engineered Excellence

Powering the Mosquito is the Breitling Manufacture Caliber B04, a self-winding mechanical movement with integrated GMT function and chronograph complication. This COSC-certified chronometer beats at 28,800 vibrations per hour and boasts a remarkable 70-hour power reserve. Whether you’re flying across time zones or timing events, the B04 ensures consistent, high-precision performance.

Chronograph and GMT Features

The chronograph tracks elapsed time with a central seconds hand, 30-minute sub-dial at 3 o’clock, and 12-hour counter at 6 o’clock. The second time zone is displayed via a red-tipped GMT hand aligned with a 24-hour scale printed on the inner dial. This dual-time capability is ideal for international travelers and aviation professionals.

Built for Real-World Adventure

Beyond aesthetics, the Super AVI Mosquito YB04451A1B1X1 is built to endure. The case is water-resistant up to 100 meters (10 bar), and the cambered sapphire crystal is glareproofed on both sides, ensuring durability and legibility in any environment. A screw-locked crown and solid pushers provide added functionality and resilience under pressure.
