A very heavy sturdy and Soviet era clock. Built for the Russian navy, circa 1960, the instrument has been fully serviced. The sweep second hand in red has been repaired in the past and I would advise this is pulled off when when winding the clock. I have seen these in the past where the 'tail' of the second hand has been removed to enable it easier to wind the clock. I find it easier to simply take it off and refit when the clock has been fully wound. 
There are substantial fixing positions at the back and it comes with the original key. Looks all nice and original with its grey finish
Overall diameter 208mm, 163mm o'all at the front  and dial 142mm. 77mm deep.
