The new Breitling Avenger Blackbird is more robust version of the Avenger Blackbird 44.
Both the 48 and 44 mm versions share the same design, same dial, and same automatic caliber 17 (ETA 2824) movement.
The differences are in the case dimensions, weight, and water-resistance rating. The 48 mm model is 4 mm larger in diameter and 1.70 mm thicker, while weight has increased by 17.50 grams. With the additional size and weight, the Avenger Blackbird gains an additional 100 meters (or 328 feet) of water-resistance.
The Avenger Blackbird, which we previously talked about here, comes with a sturdy military-type Teflon-coated black textile strap. (Ref. V1731010.BD12.100W) The retail price is $5105.
