This digital Chess Clock features an optional 5 second time delay, and optional sound.
Length: 6 3/8"
Depth: 2 5/8"
Height: 4"
Requires: 2 AA Batteries
Delay: The Delay mode adds incremental time to each side of the clock. If one player takes 5 seconds or more it will add 5 seconds to the player's time after he or she has made their move. If a player takes less than 5 seconds to make their move, then it will simply add the number of seconds taken by that player. This is an excellent feature and the advantage of an analog clock over a digital clock as it allows a game to finish based more on position rather than simply running out the clock.
