With the Avenger II 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 it 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. REF. a1338111.C870.157S Breitling's bread & butter, tried & tested chronograph movement. Based on Valjoux / ETA 7750. Versions with both date as well as day & date exist; most of the B13 however only display the date.
