Wholesale Chess Basic Digital Chess Clock This digital clock is perfect for chess and other games that require countdown, count up, bonus, and delay times. It's lightweight and small in size, so it fits in most bags conveniently and is easy to take to and from club or tournament events. Setup is very easy on this clock, so even beginners can learn to use it quickly. If you want to use it in count-up mode, simply turn it on and begin! For countdown situations, enter setup mode, simply set the desired time, and play. This clock supports bonus/increment time (also known as Fischer time) up to 59 seconds per move, and it also supports delay time up to 59 seconds per move. Important Note: You can set either bonus/increment time OR delay, but not both. Each side of the clock can start with different time, including different bonus/increment and delay time. In the setup mode, you can easily select a time for both sides, or change it by side if desired. An audible alarm when time expires can be turned on or off, depending on your preference or tournament rules. The clock runs on 1-AA battery (not included). It is great for all games and events where only one time control per game is required, making it perfect for clubs, schools, beginners, and casual players.
