Apologies if this question is not within the recognized scope of this forum. I am wondering what the below might be. Some kind of clock?

what is it?

EDIT - Sorry for not giving more information. It was on the wall in a room of a formerly KGB-run hospital in Kiev. As it is not readily recognizable, I guess it may have some medical purpose.

The frame is from the highly recommended documentary 'The English Surgeon'.

    It is very intriguingly. Where did you find this image? Jan 1, 2016 at 12:45

    Looks like a frame of a movie. In this case it should be related to movie's plot.

  • Dmitry points me in the right direction. I think it may be a eyesight test for patients suspected of papilledema.

  • Can it be a way to pick different cipher "keys"? sort of like when you know the time - you know the key... or maybe I watched too many movies :)

The Russian alphabet goes АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯ, so you can see that it's a selection of the letters arranged in alphabetical order, starting from Б on top and going clockwise. Why these particular twelve letters is anyone's guess. They don't correlate in any obvious way to numbers on a clock. If it's some kind of a combination lock or code dial, it might have parts missing. Also it might just turn out to be a faux-Russian prop from some foreign movie.
