It's a mechanical chess clock, made mostly of wood and metal. An electronic one would probably allow you to set times with more precision, but this clock has no batteries to replace, no digital display, no computer screen, no wifi, and it doesn't report your chess moves to the government, it just keeps track of you and your opponent's playing time. I have only used it for a few hours so far, but so far it is excellent.
The clock itself is made out of wood. Front crystal covers are made of plastic, so are the top buttons. Although it looks great and sturdy it's really not. Buttons on top are plastic so make sure to press them with your fingers NOT Chess Pieces, or you will break it. I suggest to keep it in its box when not in use. Do not reuse the top button holders, since they clip really tight and you could break the top buttons with the constant installing and removing.
If you change them for metal ones you could use the holders. (And yes I suggest you change them if you know what you are doing).
I would rate it 7 out of 10.
This clock have the winders so stiff. It’s very hard to move the clock on the desire game time. I have to purchased another analog clock chess. I guess for the price it’s what you get. This clock is made in China.
I ordered a Garde championship analog clock. Made in Germany now I’m very happy.
