The Casio G-Shock G-LIDE GBX-100-8 is a tough, smartphone-linked digital watch from the G-LIDE sports line, specifically designed for surfers, extreme sports fans, and fitness enthusiasts who require detailed tide and training data.

The AQ-S820W-5AV is Casio’s answer to those who want G-Shock functionality in a slimmer, more lightweight package (only 46g). The "5AV" designation refers to its earthy khaki/brown resin strap and black bezel, giving it a distinct military or "field" look. While it utilizes a resin crystal to keep costs down, the recessed dial design provides natural protection against scratches, making it one of the best value-for-money "all-rounder" watches on the market today.

The good-looking design and utility color of this Casio G-Shock model maximizes coordination possibilities with both everyday fashions and training wear. Function-wise, this watch links with the G-SHOCK Connected phone app to provide access to a number of functions that enhance workouts. Daily health and fitness support functions include a 3-axis accelerometer that keeps track of step counts, a Multi-Timer that lets you create up to 20 timer combinations of five timers each, memory for up to 200 lap records, and more. The app also makes it possible to maintain step count logs with five exercise intensity levels, to calculate the calories you burn, to specify a daily step target, to create timer combinations and send them to the watch, to store stopwatch measurement data, to view data, and more. All of this combines to help you plan and record your workouts, making them more effective and enjoyable. Other features include app-based auto time setting correction and other features for more efficient timekeeping, and an Auto LED Light to facilitate workouts in areas where lighting is dim. Back wings on the inside of the bands where they connect to the case, a new band ring shape that prevents sliding, and more band holes to allow better tightness adjustment, all add up to a more comfortable fit. You can make fine adjustments to the band size.
