Breitling Avenger II Seawolf Automatic Watch A17331 Yellow Dial Date COSC Wristwatch

Watch Overview

The Breitling Avenger II Seawolf (Ref. A17331) is a modern professional-grade dive watch built for extreme conditions — rated to 3000 meters (10,000 feet) of water resistance. Its bold 45mm stainless steel case features a unidirectional ratcheted bezel, screw-down crown, and a screw-down case-back. The standout yellow dial offers excellent visibility, with luminous Arabic numerals and baton markers, a black minute track, and a date aperture at 3 o’clock. A domed sapphire crystal and black rubber strap offers comfort and durability in demanding environments.

Powering the watch is the COSC-certified Breitling 17 automatic caliber — a robust 25-jewel movement operating at 28,800 vph with hacking seconds, quick-set date, and a 38-hour power reserve. The movement is protected by a helium escape valve, underscoring the watch’s saturation diving capability. This example is in good condition, showing light wear consistent with use but retaining strong lume, sharp case lines, and a clean dial. Fully inspected and authenticated by our in-house watchmaker, this Seawolf is a serious instrument for professionals — or an unmistakable statement piece for the collector drawn to overbuilt, high-performance watches.

History & Legacy of Breitling

Breitling is a renowned Swiss luxury watchmaker founded in 1884 by Léon Breitling in Saint-Imier, Switzerland, and now based in Grenchen. Known for its aviation-inspired designs and precision chronometers, Breitling has long been associated with the world of flight, dating back to World War I when it supplied military forces with cockpit instruments and chronographs. Originally focused on high-precision instruments for industrial and scientific use, the brand earned a reputation for technical excellence and reliability. While Breitling historically relied on movements from esteemed suppliers like Valjoux, ETA, and Venus, it took a major step forward in 2009 with the development of its in-house B01 caliber—a self-winding, column wheel chronograph movement used in flagship models such as the Chronomat 01 and Navitimer 01. With a legacy as intricate and storied as the movements it houses, Breitling continues to soar as a leader in Swiss watchmaking.
