DGT North American is one of the top chess clocks on the market. Made specifically for the US market, it has become the mainstay at all the top chess tournaments. Handles all the FIDE and US Chess Federation time controls. Blue with a off-white rocker arm and red buttons, this chess timer screams USA.
This clock uses 2 AA batteries (included). Relatively easy to program with a ton of pre-sets listed on the bottom of the clock. The manual is well written and easy to understand.
Check out my YouTube channel for videos on how to program this clock for your tournament settings. If you are running a tournament and are one of my customers, I can make a video for you to help out your Tournamnet Directors.
