Chess clock with a digital display |
摘要 |
By means of an electronic digital display, the remaining playing time of each player is displaced in minutes and seconds, so that a brief time check is possible at any time. On account of the accurate time display, therefore, there is also no longer any need for separate chess clocks for high-speed games.
