Breitling Avenger II Seawolf Stainless Steel 45mm Volcano Black Leather Strap

The Breitling Avenger II Seawolf is a purpose-built diver’s watch that pairs an imposing presence with professional-grade performance. Crafted in stainless steel and sized at 45 mm, it’s designed to stay reliable under the harshest conditions—from deep-sea explorations to high-intensity missions on land.

Key to its rugged capability is a 3,000-meter (10,000-foot) water resistance rating, paired with a unidirectional rotating bezel for precise dive timing. A screw-lock crown with a non-slip grip ensures security at depth, while a helium escape valve helps equalize pressure during saturation dives. Inside, the COSC-certified self-winding Breitling caliber B17 drives hours, minutes, seconds, and date with dependable accuracy.

Legibility is engineered for real-world use: the Volcano Black dial features luminescent hands and markers, protected by a sapphire crystal with anti-reflective coating to reduce glare underwater and in bright light. The case back is solid for added strength, and a 22 mm lug width ensures a robust strap connection that feels secure during intense activity.

Primary features and benefits

• Extreme depth rating: water resistance to 3,000 m (10,000 ft) for serious professional diving and adventurous exploration.
• Rugged, corrosion-resistant construction: stainless steel case and bezel built to withstand saltwater, pressure, and daily wear.
• Unidirectional dive bezel: precise, single-direction timing to keep you safe during dives.
• Helium escape valve: automatically vents helium during saturation diving to protect the integrity of the watch.
• COSC-certified B17 movement: automatic chronometer-grade reliability for timekeeping you can trust under load.
• Legibility in all conditions: Volcano Black dial with luminescent markers and anti-reflective sapphire crystal for clear reading at a glance.
• Date function: convenient daily reference without cluttering the dial.
• Secure strap option: calf leather strap in brown with folding clasp, combining comfort and a sophisticated contrast to the steel case.

Who this is for

Ideal for professional divers, aviators, outdoor adventurers, and watch enthusiasts who demand a timepiece that transitions from rugged environment to refined everyday wear. Its bold 45 mm presence communicates capability, while the internal mechanics and finishing speak to true Breitling craftsmanship.

Why it stands out

Few watches strike the balance between extreme performance and everyday wearability like the Avenger II Seawolf. Its 3,000-meter depth rating and helium valve set it apart from standard dive watches, while the COSC-certified B17 movement guarantees precision. The Volcano Black dial adds a distinctive, legible aesthetic, and the brown leather strap offers a refined complement to the steel case that suits both service and leisure settings.

Care and maintenance tips

• Rinse the watch with fresh water after exposure to saltwater, then dry with a soft cloth to preserve the leather strap.
• Have the crown and seals checked during regular service intervals to maintain water resistance.
• Avoid exposing leather straps to excessive moisture; consider switching to a metal or rubber strap for extended underwater use.
• Periodic servicing of the B17 movement will safeguard chronometer performance and longevity.
