1989
Aerochron C046
The same year that the Wingman debuted, Citizen launched the Aerochron. The Aerochron also had an analog time display for local time, combined with an LCD multi-function display, as well as a flight bezel – and it had something new. It was the first quartz watch with an altimeter, which also provided barometric pressure readings, and could even provide correct altitude information for flying under visual or instrument flight rules.
Finally, a feature of almost every Promaster aviation watch is the slide-rule bezel. Somewhat mystifying at first to non-initiates, the slide-rule bezel is actually a mechanical calculator, which allows pilots to calculate critical values such as rate of climb and descent, time and distance calculations, and fuel consumption. The design of the slide-rule bezel is derived directly from one which pilots are still required to learn to use: the E6-B flight computer, or “whiz wheel,” the use of which is a critical part of aviation training and which can still be an essential backup to flight instruments if instrument failure should occur in an aircraft.
Happy to post at buyer's expense.
