AChS-1V Aviation Clock

My AChS-1V aviation clock also known as a board or panel clock. Typically found in an aircraft instrument cluster.




No, it doesn't ride with me in the car... just sits in the kitchen of my country home.


It is a good time measuring device. It is actually a chronograph -- has a stopwatch. And it also has a "flight time" counter. You wind it once and it goes up to 3 days on full winding.


It's been in the family for 30 or something years. And probably did some service on an actual plane before that (may be not).


There are two version of the AChS-1V clock -- this one which is the more recent of the two and the other one where it says "2 days" on the face in white paint. It is possible that the clock is still in production [in Russian].



There is lume on the hands and indexes which glows green in the dark.
