With the Avenger Seawolf, Breitling has accomplished a major technical exploit by producing a professional diver’s watch that is water-resistant to 3,000 meters (10,000 ft/300 bars). Built on the sturdy Avenger platform, the Seawolf is also a functional success, since its dimensions have been kept very reasonable and offer perfect ergonomics, despite the technical constraints imposed by the need to withstand pressure of 300 bars. To achieve this, Breitling used numerical simulations to develop perfect geometry for the case. The Seawolf also has a safety valve enabling it to balance the differences in pressure inside and outside the case. As soon as internal overpressure reaches approximately 3 bars, the valve automatically evacuates the helium built up during prolonged stays at great depths and thus avoids the case exploding.
