Features 1、Multifunctional Timing Mode: Supports both count up and countdown modes, with a maximum setting of 9 hours, 59 minutes, and 59 seconds. Whether for formal competitions or daily training, it can meet various time control requirements. Users can also customize the reward time and delay time for each step, with a maximum of 59 seconds per step, allowing for flexible adaptation to different competition rules. 2、Smart Reward and Delay Functions: The built in reward and delay features allow users to customize the reward time and delay time for each step. This flexibility enables the chess clock to adapt to various competition rules, easily handling games that require reward time for each move as well as those that need delay time for each move. 3、Clear Alerts and LCD Display: When one player loses, the chess clock emits a continuous "beep beep beep" sound for 3 seconds to notify both parties that the match has ended. This alarm feature not only ensures fairness in the competition but also prevents misjudgments caused by missing the time limit. The chess clock is equipped with a large sized LCD display, ensuring that the digits are clear and easy to read, even during prolonged viewing. 4、Memory Function and Battery Capacity Indicator: When the chess clock is turned off and then turned back on (without a power cut), it retains the last used rule parameters before shutdown, eliminating the need for reconfiguration. Additionally, when the battery is running low, a warning symbol will appear at the top center of the display, reminding users to replace the battery in a timely manner to ensure the smooth progression of the match. 5、Stable Performance: The circuit board uses an automated soldering process, securely fixing all components to the panel, making it less susceptible to damage during transportation. Each chess clock contains two independent chips (for black and white), which ensures the stability of the clock. When a button is pressed, a notification light illuminates, and the display arrow points to the side making the move.
