Watch MRG-B5000BA-1DR

The Watch

Founded in 1946, Casio began its journey making calculators. Driven by a passion for innovation, the brand moved into watchmaking and became one of the industry's leading names, consistently delivering timeless, cutting-edge timepieces. Built for every style, its models combine quality, durability, and impressive functionality. G-Shock is its most iconic line - purpose-built to withstand the most extreme conditions, just like the MRG-B5000BA-1DR. Inspired by the original G-Shock and crafted from premium metals with meticulous finishing, this watch is instantly recognizable for its reliability, functionality, and bold aesthetic. It features an octagonal case crafted from ultra-hard titanium based on "Ti64" with a Multi-Guard structure integrating four-corner suspension components combining T-bars and flat springs with a resin buffer, delivering exceptional shock absorption. The case measures 49.40 mm wide, 43.20 mm long, and 12.90 mm thick. Weighing just 114 g, it sits featherlight on the wrist for all-day comfort. The case is paired with a bezel built in multiple parts from a Cobarion alloy - four times harder than pure titanium - and composed of 25 individual components, each polished separately for a flawless, platinum-like finish. On all four corners of the case, blue ion-plated components are applied over a DLC carbon coating. These blue accents draw from a distinctly Japanese artistic color called "Ao-zumi" - a deep blue variant of the black Sumi ink used in traditional Japanese calligraphy and painting. The flat sapphire crystal protecting the dial from scratches features an anti-reflective coating on its inner surface for optimal legibility. Functions are controlled via 4 pushers, placed two on each side. The ensemble is completed by a screw-down caseback with a carefully brushed finish and a hobnail pattern bearing the series name in relief - a fantastic decorative touch. This caseback delivers a solid water resistance of 20 ATM.

The Dial

The dial delivers a clean, minimalist look with a digital display for effortless readability. The black background features an eye-catching brick pattern framed by a blue bezel achieved through vapor deposition, giving it a relaxed yet refined appearance. This border is elevated by a gold-tone line that echoes the collection name and the line marked on the dial, as well as the labels guiding button function use. At the center, the LCD screen delivers the contrast combination Casio favors for enhanced legibility - further boosted by a Super Illuminator, a fully automatic high-brightness LED backlight for crystal-clear visibility in the dark.

Features

Bluetooth® Smart

The watch is equipped with energy-efficient Bluetooth® technology, enabling data exchange with the press of a button. The Bluetooth® function wirelessly connects the watch to a smartphone, unlocking a wide range of highly convenient features.

Smartphone time

When the wall clock is paired with a smartphone, the time is set automatically and displays the current time anywhere in the world.

Super Illuminator

A single press of a button illuminates the dial in vibrant, on-trend colors.

Solar powered

This solar-powered watch integrates photovoltaic cells into its dial to capture light energy and autonomously power the quartz movement. Surplus energy is stored in a solar battery, keeping the watch running even in complete darkness. When not wearing it, simply place it near a bright light source to keep it charged.

Automatic time synchronization via radio-controlled signals (EU, USA, JPN, CHN)

Whether you're in Europe, North America, Japan, the vast territories of Canada, Central America, or China - once the watch is set to the local time zone, it receives the corresponding radio signal and always displays the exact date and time. In many countries, it automatically switches between daylight saving time and standard time.

Button beep on/off

The button beep can be turned off using the mode button. Once disabled, no beep sounds when switching between functions. However, any programmed alarms or countdowns remain active even after the button beep is turned off.

It offers up to 10 months of battery life under normal use and 22 months in storage under total darkness with the power-saving function enabled.

The Bracelet

This watch is paired with a beautiful and durable bracelet crafted from a titanium DAT55G alloy approximately three times harder than pure titanium. Exceptionally comfortable, it features a single row of Y-shaped links enhanced with a DLC carbon coating and fitted with blue ion-plated screws. These blue accents evoke a sense of calm strength and lend a striking edge to the design. The bracelet is secured by a superb triple folding clasp worthy of a great Japanese manufacturer, complete with pushers and a locking switch that prevents accidental release.

Water Resistance

With water resistance of 200 meters - or 20 ATM in the precise language of watchmaking - this watch is built for shallow-water diving. It handles showers, baths, ocean swims, and casual pool dips with ease. That said, our Ocarat watch experts have hand-picked dedicated 30 ATM models for professional scuba diving, available on our site with a quick search. One last reminder: avoid operating the pushers or crown during any water activity.
