Casio MRG-B5000B-1DR Watch

The Watch

A Japanese manufacturer, Casio delivers timepieces that combine ruggedness and technical excellence. With unmatched expertise, it crafts watches with refined, sporty designs built for your greatest adventures - using solid, durable materials that make every model a benchmark for performance under physical strain. As a tribute to its first G-Shock watch, Casio presents the Casio MRG-B5000B-1DR, built from cutting-edge materials with meticulous finishing. Its sleek design centers on a case crafted from extremely hard Ti64-based titanium, delivering undeniable durability. Octagonal in shape, it measures 43.20 mm wide, 49.40 mm long, and 12.90 mm thick. It also features a polished gleam and a DLC (Diamond-Like Carbon) coating that gives it its striking metallic black tone. The bezel matches the case dimensions and is crafted from Cobarion® cobalt-chrome alloy - four times harder than pure titanium. Made up of 25 individually polished components, it incorporates flat springs and silicone buffers for enhanced shock resistance. It surrounds an anti-reflective sapphire crystal that protects the dial from impacts while ensuring effortless legibility. Around the case, four pushers are mounted in pairs to navigate the watch's various modes. Gold-toned, they feature gold ion-plated finishing, as does the caseback. Finally, this watch weighs 114 g and features a screw-down caseback ensuring water resistance to 20 ATM.

The Dial

This dial is thoughtfully designed for clear, precise timekeeping. Clean and refined, it features a brick pattern that highlights its digital display against a grey background. The inner bezel shows markings for the various functions. With its automatic LED backlight, it delivers optimal legibility whenever needed. It clearly communicates hours, minutes, and seconds, along with multiple additional features such as world time, battery level, and countdown timer.

The Functions

Bluetooth® Smart

The watch is equipped with energy-efficient Bluetooth® technology for seamless data exchange at 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 always displays the current local time worldwide."

Super Illuminator

A single button press lights up the dial in vibrant, on-trend colors.

Solar power

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

Automatic time sync via radio-controlled signal reception (EU, USA, JPN, CHN)

Whether 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 picks up the corresponding radio signal and always shows the exact date and time. In many countries, it automatically switches between summer and winter time and back.

World time function

The world time function displays the time across 29 time zones and major cities worldwide.

The Strap

This bracelet is expertly crafted to provide a secure and comfortable fit. Made from a DAT55G titanium alloy - three times harder than pure titanium - it delivers exceptional durability, making it the ideal companion for all your activities. It also features a DLC (Diamond-Like Carbon) coating that gives it its sleek black tone, pairing effortlessly with any color. The bracelet is equipped with a triple push-button deployant clasp with secure locking, ensuring safe and easy handling.

Water Resistance

With water resistance to 20 atmospheres - equivalent to 200 meters - this model can confidently be called a dive watch. Our watchmaking experts agree: while this timepiece is more than up to the challenge of showers, baths, lap swimming, freediving, and recreational scuba diving, it is not designed for extreme deep-sea diving where pressure could compromise its water resistance. For professional divers pushing depth limits, we recommend exploring models rated at 30 atmospheres or more. We also advise against operating the pushers or crown while submerged, to preserve a perfect seal.
