AChS-1 is a 12-hour dial clock with special chronograph and an 12-hour elapsed time features designed for use as a navigational instrument in aircraft. This gauge is not affected by the time-zone boundaries. It is completely synchronized with MSFS internal timer, so can be used even when time acceleration is used.
The functional features of the elapsed time clock were;
1) a 12-hour dial;
2) a chronograph system for measuring and recording short intervals of elapsed time;
3) an elapsed time mechanism entirely independent of the chronograph, for measuring long intervals of time (in both hours and minutes).
The Molnija clock and watch factory was opened on November 17, 1947.
The company’s main customer was then the Soviet Union Department of Defense, providing them with wrist watches, pocket watches and table clocks. Unique clocks were also produced specifically for use in Soviet tanks, fighter aircraft, submarines and, eventually, spacecraft.
