CASIO G SHOCK G-SQUAD GBD-300-1
Introducing the GBD-300 product category for your active lifestyle — a tough, sport-focused G-SQUAD designed to make training more enjoyable.
Enhance your workouts with the GBD-300, packed with practical features to support running and other training activities. With an accelerometer, distance tracking, smartphone connectivity, high-resolution display, and more, this G-SQUAD model is ready to meet your needs — from daily health management to building endurance.
Use the GPS function of your paired smartphone to calibrate distance measurements. Once calibrated, the watch can measure running distance more accurately even when not connected to your phone. In addition to automatic lap counting, the watch tracks running pace and automatically records times for preset distances. Access the dedicated app to visualize data, review personal records, and easily manage Life Log data and activity history.
Set the watch to vibrate and alert you about elapsed time, calories burned, and other training goals. You can also enable notifications so you never miss phone calls, emails, or social media alerts.
The display features a Memory-in-Pixel (MIP) LCD with Super Illuminator backlight. Combined with the auto light function — which illuminates automatically when you tilt your wrist while running — the GBD-300 ensures excellent visibility, even at night.
With a shock-resistant structure that positions the case between the front and back bezels, the GBD-300 achieves one of the slimmest profiles in the G-SQUAD lineup. The band is made of soft urethane for a secure and comfortable fit, featuring 5 mm interval adjustment holes for more precise sizing across different wrist sizes. Soft urethane and flexible fine resin on the underside of the watch enhance comfort, even during intense movement.
Key resin components used in the case, band, and other parts are made from bio-based resin — a material expected to help reduce environmental impact.
