Casio G-Shock DW-5600RL-1 Digital Black Resin Watch

Heritage in a Square Frame

We begin with the silhouette you already know this is the DNA of the original G-Shock “square” shape, the DW-5600 line. The DW-5600RL-1 carries forward that legacy: hard-edged, purposeful, built to last. It’s the sort of design that whispers toughness, not screams it.

Materials & Build

Casio has swapped in bio-based resin for both the bezel and the band, reducing reliance on purely synthetic materials without compromising durability. The case and bezel are resin (with bio-resin elements), and the band follows suit. The glass is mineral, standard for this line. This model maintains the 200-meter water resistance that’s been part of G-Shock’s reputation enough for swimming, snorkeling, and whatever daily Abuse™ your life brings.

Size & Dimensions

The watch measures approximately 48.9 × 42.8 × 13.4 mm. That height (thickness) gives it presence, but the compact width/length helps it sit well even on smaller wrists. It’s substantial enough to feel solid, yet wearable.

Movement & Power

Powered by a quartz module, with reliable battery life about 5 years from a standard CR2016 battery. This isn’t one of Casio’s solar or radio-sync models, but you get proven digital performance: stopwatch, timer, alarms, and a full auto-calendar through 2099.

Display & Features

The dial is digital, with standard G-Shock utility:

• LED backlight (“Super Illuminator”) with afterglow for easy night reading.
• Multi-function alarm(s), hourly time signal.
• Countdown timer (ranges from 1 second up through 24 hours), stopwatch measured to 1/100-second.
• Format flexibility: 12/24-hour.

Color, Design & Aesthetic Touches

True to the DW-5600’s roots, this model sticks to a minimalist black dial. The design adds pops of G-Shock’s classic accent colors: red (for grit/challenge), blue (for water resistance), and yellow (for shock resistance) small but meaningful details that nod to G-Shock’s heritage.

What Makes It Special

The DW-5600RL-1 straddles nostalgia and eco-awareness. It’s not trying to be futuristic; it’s honoring what made G-Shock iconic (ruggedness, clarity, utility), while gently updating the materials to be a bit more responsible with bio-resin. For someone who wants an “everyday rugged digital” with history, this is a strong choice.
