A large analog desk clock with 2 buttons and 3 scales - time, flight time and chronometer. A close replica of the famous Russian aircraft clock ACS, which has been used for both civil and military purposes since the 2WW.
The time is measured with 3 hands - hours, minutes and seconds. The timer for flight time has 12 hours and a minutes hand. The timer for intervals has 60 minutes and a seconds hand. The timers work separately or together. The face is black, hands are whitish. In night mode the hands get greenish like in the real clock.
