Portable Mechanical Chess Clock

Size: 15 cm (L) × 5.5 cm (W) × 9 cm (H). Constructed from responsibly harvested wood and engineered plastic. Surface finish: Unpainted natural wood grain. Functionality: Purely mechanical — wind once to power; press button to toggle timing between players; supports both ascending (count up) and descending (count down) modes. No battery, no USB, no firmware — just gear-driven precision delivering ≤±1 second daily variance. Suitable for use in UK schools, community centres, public libraries, and local chess leagues where simplicity, longevity, and regulatory compliance matter. Care guidance: Keep away from direct sunlight, moisture, and magnetic sources to preserve timing integrity and wood finish. Designed for repeated handling — smooth edges, balanced centre of gravity, and quiet operation ensure minimal disruption during serious play.
