The Casio G-Shock GD100-1B is a rugged digital watch built for durability and high visibility, with a dark negative digital display set inside an all-black resin case. Featuring a high-brightness Super Illuminator LED backlight, it's easy to read even in low light, while the shock-resistant construction and 200-meter water resistance make it ready for demanding outdoor use. At 55.0 x 51.2 x 17.4mm, it has a substantial, technical wrist presence.  Part of Casio's iconic G-Shock lineup, the GD100-1B loads in genuinely useful features: 1/100-second stopwatch, a 24-hour countdown timer, world time across 31 time zones (48 cities plus UTC), 5 independent alarms, and a full auto-calendar programmed through 2099. With a 7-year battery life, it's a low-maintenance, do-it-all digital watch built for anyone who wants toughness and function over flash.
