The Casio G-Shock G-SQUAD GBD-300-1DR represents the next evolution of tactical sport wristwear. Engineered specifically for fitness enthusiasts and urban runners, this powerhouse combines Legendary G-Shock toughness with modern smart fitness capabilities. Whether you are training for a marathon in Colombo or tracking your daily activity routines, the GBD-300-1DR delivers unmatched accuracy, rugged reliability, and sophisticated digital functionality. Available in Sri Lanka at Ranasinghe Watch Works, this timepiece stands as a testament to Casio's relentless pursuit of innovation and endurance.

Premium Design

Featuring the slimmest profile in the G-SQUAD lineup, the GBD-300-1DR showcases a dual-bezel construction that provides maximal shock protection without adding bulk. The front bezel takes on a sharp, casual octagonal silhouette, while eco-conscious bio-based resin components reduce environmental impact without sacrificing durability. The sleek black aesthetic offers a versatile, tactical look that seamlessly transitions from intensive gym sessions to everyday urban wear.

Dial Features

At the core of the watch interface is a high-contrast Memory-in-Pixel (MIP) LCD display. Built for maximum readability under intense direct sunlight or low-light conditions, the MIP display clearly presents distance, pace, step counts, and lap times. Illuminated by a Super Illuminator high-brightness LED backlight with an auto-light switch that activates with a flick of the wrist, night runs become safer and easier to track.

Case Features

Engineered with a glass fiber-reinforced resin inner case sandwiched between front and back bumper bezels, the case structure absorbs severe impacts effortlessly. Measuring 48.9 × 47.4 × 14.9 mm and weighing just 60 grams, it remains lightweight on the wrist while guaranteeing 200-meter water resistance.

Movement

Powered by a precise digital module (Module 3568), the watch utilizes a standard CR2032 battery offering up to 2 years of battery life. Paired with Bluetooth® Smart Link, the watch automatically syncs time with your smartphone, adjusting across 38 world time zones with zero manual effort.

Strap/Bracelet

Crafted from flexible, soft bio-based resin, the strap is built for high-energy motion. It features fine adjustment holes placed at 5mm intervals for a tailored fit on wrists sized between 145mm and 215mm. Flexible resin under-case covers keep the band from sticking to sweaty skin, providing all-day breathability.

Water Resistance

With a rated water resistance of 20 bar (200 meters), the GBD-300-1DR is fully prepared for heavy rainfall, high-humidity environments, swimming, and ocean sports.

Comfort

Thanks to its lightweight 60-gram frame and slimmest-ever G-SQUAD profile, this watch eliminates wrist fatigue. Curved resin back covers align naturally with your wrist bone for a stable fit during rapid movements.
