Here is the, “why”:
What I want in a chess clock is nothing fancy. It needs to keep the game time accurately.
it needs to have a display that is easily seen at a quick look.
The button system needs to be easy to see and find for the push. It also needs to have a definite action so there is no doubt it has been pushed on the first push.
It should have either lights or other ways to see which player is on the move And this needs to be visible from a distance.
It needs to be easy to set, with minimum attention.
Of course it needs to be durable in build.
The Chronos II fits this description. However that clock is not being sold at this time.
The V-Tek 300 also has what I want. And it is for sale but expensive.
I currently use The V-Tek for most of my tournament games. I also have a few Chronos clocks that I also use.
The DGT 3000 is pretty good and you can find it at a good price as well.
Which one are you picking and why?
