With the selfwinding Avenger Seawolf model, Breitling has accomplished a first-rate technical performance by producing a professional diver's watch that is water- resistant to the fabulous depth of 3,000 meters (10,000 ft). Built on the sturdy Avenger platform and equipped with a decompression valve, the Seawolf is also a functional success, since its dimensions have been kept very reasonable and offer perfect ergonomics despite its vocation for major accomplishments. To achieve this, Breitling used numerical simulations to develop perfect geometry for the case.
