Wind-Up Chess Clock Count Up Count Down

Dimensions: 15 x 5.5 x 9 cm. Weight: Optimised for portability and tabletop grip — light enough to carry daily, weighted enough to resist sliding during intense play. Capacity: Dual-movement mechanical system enabling independent count-up (e.g., tracking thinking time per move) and count-down (e.g., 15+10 increment formats). Material: Natural wood finish over reinforced ABS plastic core — offers tactile authenticity and drop-tested resilience. Core functionality: Manual wind-up operation — no battery compartment, no charging port, no firmware updates. Timing starts/stops via crisp, spring-loaded buttons with audible click confirmation — eliminating uncertainty about activation status. Timekeeping calibrated to ≤1 second daily error — tested across three consecutive days under controlled lighting and temperature — meeting expectations for informal rated play in UK and EU amateur circuits. Internal gears are lightly lubricated for smooth torque transfer and minimal wear over 5,000+ actuations. Use context spans casual home play, inter-school competitions, senior citizen chess groups, and volunteer-run community hubs — all benefitting from its simplicity, silence, and lack of technical barriers. Longevity depends on adherence to care guidance: store in dry, shaded cabinets; wipe with soft cloth only; never immerse or spray with cleaners.
