It includes applied steel faceted baton hour markers attached to luminous square pips, around a luminous white minute/fraction-of-a-second scale. There is an oversized applied steel Arabic numeral at 12 o'clock. It has a perimeter luminous white and red chapter ring for indicating IFR/VFR flight levels. There are three steel-rimmed white recessed subsidiary dials with black markers, Arabic numerals, and black steel indicator hands with luminous inserts, including a running constant small seconds register at 3 o'clock, a 24-hour GMT second time zone dial at 9 o'clock, and at the 6 o'clock position is a minute and hour chronograph totalizer for timing periods longer than 60 minutes, providing elapsed time at a glance rather than having to read 2 separate dials.
