Built around a 45mm stainless steel round case, the Avenger II Seawolf features a convex sapphire crystal glare-proofed on both sides and a solid case back. The Volcano Black dial is laid out with Arabic numeral hour markers, adjacent luminous dots, and large luminous indexes at 6, 9, and 12 o'clock, while polished hour and minute hands carry luminous fill and the seconds hand is tipped in red with luminescent fill. A date window sits at 3 o'clock, and the printed white minute track circles the perimeter.
The unidirectional rotatable stainless steel bezel carries engraved Arabic numerals and indexes, and a helium escape valve on the case side allows pressure equalization during deep-dive decompression. A steel screw-down crown with non-slip grip and screw-locked double gaskets contribute to the watch's 3,000m/10,000ft water resistance rating. The brushed stainless steel bracelet fastens with a fold-over clasp featuring a safety release.
Power comes from the COSC-certified Breitling Calibre 17 automatic movement, housing 25 jewels and offering a power reserve of approximately 38 hours. Offered unworn with authorized-dealer protective plastics removed, the watch is accompanied by a booklet and carries a Breitling warranty. The original Breitling box and papers are included.
