BOHEMIA (Bohemia) West German Chess Clock

Vintage analog chess clock.
*With original box

I acquired this as a vintage item in the past and have kept it carefully at home. I confirmed that it operates using the top buttons on the left and right sides. I did not use it myself, but since it is a very old item, there may be minor scratches and wear and tear if you examine it closely. Considering its age, it's in quite good condition with little sign of use.
(I checked and found no major damage, but there may be oversights. Please refer to the images for the condition of the item.)
However, the box has deteriorated with age and has scratches, stains, discoloration, and dirt.

Please refrain from purchasing if you are concerned about the details, as this item has been stored by an individual for a long time.
Thank you.
