DGT1002 is the simplest chess clock with bonus options available. Simply press + or - to set the times and then start the game! A great little affordable clock with a large display and clear digits. Can be used with increments.
The DGT2010 was introduced in 2007 and received the status of "Official FIDE Chess Clock" in June 2008, after tests by four top-level arbiters concluded that the clock is in full accordance with all FIDE rules and regulations. This clock has many advanced features, including the ability to use the many preset time options, as well as creating your own manual setting, with increments if desired.
