Titanium MRG 2100 Watch MRG-B2100R-2ADR

The Watch

Casio is a Japanese brand founded in 1946. Its timepieces - celebrated for their durability, functionality, and bold design - appeal to adventurers, athletes, and everyday wearers alike. With its G-Shock collection, Casio delivers ultra-tough, feature-packed models built for the most demanding users. Today, the brand introduces its new Titanium MRG 2100 Watch MRG-B2100R-2ADR, a timepiece for every occasion. Inspired by Japanese craftsmanship, it is designed for men's wrists. It features an octagonal Multi-Guard case measuring 49.50 mm in length, 44.40 mm in diameter, and 13.60 mm thick. Weighing 110 g, it is crafted from a cutting-edge Ti64 titanium alloy with a mirror-polished finish. Built from 27 individual components, it offers outstanding shock resistance. The octagonal bezel is made of Cobarion®, combining durability with aesthetics. The four corners of the case integrate ion-plated components in navy blue on a black DLC carbon base, adding depth and a pop of color to the overall design. The dial is protected by a scratch-resistant sapphire crystal with an anti-reflective coating for glare-free reading. The central elements are controlled via a black screwed crown at 3 o'clock with grooves for easy grip, flanked by two pushers at 2 and 4 o'clock. The watch is sealed by a screw-secured caseback providing 20 ATM water resistance.

The Dial

This ao-zumi dial has been carefully crafted for precise and fluid reading. Inspired by traditional Japanese ink painting and calligraphy, it incorporates unique decorative elements that evoke the traditional Japanese wood joinery techniques known as kigumi. Its undulated surface features a series of intricate openings forming a striking geometric pattern - a stunning showcase of Casio's artisanal quality. Treated with a vapor deposition finish, the metallic blue background is bordered by a minute track with baton-style hour indices. Three centrally placed hands ensure precise timekeeping. The slender gold seconds hand tracks the seconds, while the hour and minute hands feature a Neobrite treatment - as do the hour indices - for optimal dark-condition readability. A high-brightness white LED light ensures visibility whenever needed. A date window sits at 3 o'clock, while an additional sub-dial is positioned between 6 and 9 o'clock. This sub-dial features a small grey hand displaying the day of the week in English in a retrograde manner, along with a DST adjustment indicator. Additional indicators appear around the dial: letters (Y) and (N) between 9 and 10 o'clock indicate successful or unsuccessful time signal reception, while letters (C) and (RC) near 6 o'clock show the watch's connection to a phone and active calibration signal reception, with the seconds hand pointing in the relevant direction. Finally, the dial bears the brand name and collection name beneath the double noon index as a signature.

The Movement

Powering this timepiece is a solar movement. Thanks to its magnetic resistance, it withstands vibrations, ensuring reliable performance across the hands, date window, sub-dial, and all other functions. This Japanese movement, equipped with Casio's proprietary Tough Solar technology, delivers an accuracy of ±15 seconds per month. Its rechargeable battery provides a power reserve of 5 months - and up to 18 months when fully charged and stored in complete darkness with the power-saving function enabled.

The Strap

This stunning Dura Soft strap, crafted from fluorinated rubber, is the perfect everyday companion. It attaches to the case via insert-molded titanium components for lasting durability and comfortable wear. The brick-pattern textured surface conforms naturally to the contours of your wrist. In black, this strap fastens with a single-push triple-fold deployment clasp in titanium and fits wrist sizes from 145 to 215 mm.

Water Resistance

With water resistance of 20 atmospheres - equivalent to 200 meters - this model earns the title of dive watch without hesitation. Our watchmaking experts agree: it's more than up to the task for showers, baths, lap swimming, freediving, and recreational scuba diving. That said, it is not designed for extreme deep-sea diving, where pressure would exceed its limits. For professional divers tackling serious depths, we recommend models rated 30 ATM or higher. Also, avoid operating the pushers or crown while submerged to maintain a perfect seal.
