Casio G-Shock Classic

Description

The Casio G-SHOCK GBD-300-7ER is a sports men's watch from the G-SQUAD line, designed specifically for active runners and fitness enthusiasts. The robust case, crafted from resin and bio-based resin, offers shock-resistant construction and is water-resistant to 20 bar, making it equal to every training demand. The high-resolution MIP-LCD display (Memory-in-Pixel) with Super Illuminator lighting ensures excellent legibility even in low-light conditions, while an automatic light function activates when the wrist is tilted.

The GBD-300-7ER connects to your smartphone via Bluetooth and uses the paired device's GPS for precise distance measurement. The watch can then calculate running distance accurately even without a smartphone connection. Automatic lap recording, calorie burn, pace and average speed are all tracked and can be conveniently managed via the CASIO WATCHES App. The soft bio-based resin strap, with 5 mm hole intervals, allows a precise fit for wrists between 145 and 215 mm.

Key Features of the Casio GBD-300-7ER Watch

  • Bluetooth Training Computer: Automatic time synchronisation, GPS-assisted distance measurement and lifelog data via the CASIO WATCHES App for comprehensive health management.
  • Extensive Sports Functions: Stopwatch, countdown timer, interval measurement, auto-pause and recording of up to 100 runs with up to 140 lap times each.
  • Bio-Based Resin Case: Shock-resistant, water-resistant case (20 bar) with mineral glass and sustainable bio-based resin material in both the case and strap.
