Casio

Since entering the watch market in 1974, Casio has revolutionized digital timekeeping with their innovative approach to functionality and durability. Their G-Shock line, introduced in 1983, redefined shock-resistant watches and has become a cultural icon. The brand's Edifice collection brings sophisticated analog-digital technology to motorsports timing, while their Pro Trek series offers advanced environmental sensors for outdoor enthusiasts. Through their constant innovation in digital technology, solar power, and radio-controlled timekeeping, Casio continues to push the boundaries of what a watch can achieve.
