The 42mm diameter round solid 3-body case, curved hooded lugs, bracelet, and knurled angled rotating bidirectional bezel, are polished. The white bezel ring with black Arabic numerals and the inner black chapter ring with white Arabic numerals are a circular slide rule for performing all airborne navigation computations including miles-per-hour. The dial is black with applied steel baton hour markers with square luminous end indices around a luminous white 1/5 second/minute scale with an outer white tachymeter scale to 750 UPH. It has steel pointed baton hour and minute hands with luminous inserts, and a red luminous center sweep chronograph hand with an arrow tip and a polished steel Breitling logo counterbalance. There are three black "pie tin" recessed subsidiary dials with white Arabi.
