The Casio G-Shock GD-350-1BDR Black Out Edition stands as a benchmark in tactical watch engineering. Purpose-built for military personnel, law enforcement officers, athletes, and outdoor adventurers, this model combines a covert stealth design with advanced timing features. Designed to thrive in demanding environments across Sri Lanka—from urban tracks to rugged trail expeditions—the GD-350-1BDR delivers instant readout performance and dependable durability. Available through Ranasinghe Watch Works, this timepiece represents an ideal blend of tactical utility, absolute shock resistance, and contemporary stealth design.

Premium Design

The design of the Casio G-Shock GD-350-1BDR is tailored for high-visibility functionality and tactical stealth. Its matte black resin exterior eliminates reflective glare, making it well-suited for low-profile military or security operations. Shock-absorbing shock wings mounted on the reverse side of the case provide exceptional wrist stability while dampening impact vibrations. The bold, angular case geometry gives the timepiece a commanding presence on the wrist without adding unnecessary bulk.

Dial Features

Equipped with a high-contrast negative LCD digital display, the dial layout of the GD-350-1BDR is engineered for clear legibility. The display is divided into distinct functional zones, featuring a dedicated circular indicator for vibration alerts and countdown tracking. To maintain readability in pitch-black environments or nighttime operations, the watch features an auto LED backlight (Super Illuminator) with selectable illumination durations (1.5, 3, or 5 seconds) and flash alert capabilities.

Case Features

Crafted from high-grade impact-resistant resin, the case measures 53.4mm × 50.8mm with a thickness of 18mm. The structure guards internal components against heavy impacts, drops, and intense vibration. A scratch-resistant mineral glass lens seals the face, protecting the display from harsh outdoor debris, sand, and accidental scrapes.

Movement

At the core of the GD-350-1BDR is Casio's Module 3403 quartz digital movement. Delivering precise accuracy within ±15 seconds per month, this digital engine powers world time tracking, high-speed stopwatch counting, multi-alarm configurations, and silent vibration alerts. The movement is powered by an extended-life CR2032 lithium battery designed to offer up to 5 years of operational service.

Strap/Bracelet

The matching black resin band is flexible, durable, and resistant to moisture and sweat. Featuring a secure double-prong buckle system, the strap fits wrist sizes from 145mm to 215mm comfortably. Integrated resin wings on the inner back cover conform smoothly to the curve of the wrist, reducing slippage during rigorous physical activities.

Water Resistance

Engineered for marine environments, wet weather, and heavy rain, the GD-350-1BDR features a 200-meter (20 BAR) water resistance rating. Whether swimming, snorkeling, jet-skiing, or navigating tropical downpours across Sri Lanka, this timepiece maintains its seals to protect internal components.

Comfort

Despite its robust exterior, the watch weighs just 75 grams. The back-case wings cushion the wrist, allowing airflow to prevent heat buildup during extended wear in humid climates.

Ideal For

• Military, security, and tactical field personnel who require silent alarm alerts.

• Fitness enthusiasts, coaches, and athletes needing a direct-access countdown timer button.

• Outdoor adventurers requiring 200m water resistance and high impact protection.

• Watch collectors seeking an authentic G-Shock model with a stealth black aesthetic.
