Dual-Side Adjustable Chess Timer

Constructed from robust ABS plastic in black finish; requires 2 x AA batteries (not included). Supports five distinct timing protocols: BASIC, BONUS, DELAY, BYO-YOMI, and COUNT-UP, with automatic transition to positive timing mode once countdown completes. Maximum user-defined time limit is 9:59:59. Each player’s time parameters can be set and altered separately — even during active gameplay. All settings are retained automatically prior to shutdown. Step counter records, displays, and allows editing of up to 999 moves. Sound feedback and device power can be toggled on or off as needed.
