MRG 2100 Titanium and Cobarion Watch MRG-B2100B-1ADR

The Watch

Casio is a Japanese brand founded in 1946 by Tadao Kashio. A true diversified powerhouse, it produces musical instruments, cameras, and timepieces alike. Its watches are renowned for their ruggedness, precision, and functionality, spanning digital, sport, and analog styles. Built to take on the demands of everyday life, they offer shock resistance that gives you total peace of mind during your most intense adventures - and advanced features that push the boundaries of traditional watchmaking. From accurate stopwatches to convenient countdowns and alarms, they keep up with your lifestyle in style. Discover the perfect fusion of style, technology, and durability with the MRG 2100 Titanium and Cobarion Watch MRG-B2100B-1ADR. Designed for bold spirits, it houses a shock-resistant octagonal case measuring 49.50 mm long and 44.50 mm wide, with a 13.60 mm thickness and a weight of 122 g. It is crafted from a state-of-the-art brushed and polished titanium alloy and features a cobarion bezel made up of 27 individual components. It boasts brilliant mirror finishes and a diamond-like carbon coating that delivers that striking glossy black look. The sapphire crystal is both anti-reflective and scratch-resistant, ensuring crystal-clear clarity and protecting the dial from potential impacts. The indicators are operated by the two gray pushers and the black crown positioned on the right side. The crown is screw-locked and slightly grooved for a confident grip. This model is sealed with a specially engraved Ti64 titanium alloy screw-down case back, delivering water resistance of 20 ATM.

The Dial

This striking dial brings an air of refined elegance to the timepiece. Set against a black background, it features a lattice pattern inspired by the traditional Japanese woodworking art of kigumi. Tiny openings allow just enough light through to generate the solar energy needed to power precise timekeeping. An Afterglow white LED ensures legibility whenever needed. The black bezel displays the minute track with delicate striations and baton indexes as hour markers. At the center, three two-tone hands sweep precisely across these indicators. The slender red seconds hand tracks the seconds, while the long and short hands indicate the minutes and hours respectively. These two gray hands feature a brushed finish with Neobrite treatment for optimal dark-condition legibility - a coating also applied to the hour indexes. For added functionality, a date window sits at 3 o'clock and an additional subdial at 8 o'clock displays the day of the week (abbreviated in English) via a gray hand. This subdial also indicates DST adjustments. Additional markers include (C) and (RC), indicating the watch-to-phone connection and calibration signal reception status respectively. The letters (Y) and (N) near 11 o'clock - pointed to by the seconds hand - indicate yes or no for time signal reception, phone connection success, time correction, and activation/deactivation of these functions. Additional display modes are available depending on the operations performed. The dial is signed with the collection name and brand name beneath the 12 o'clock index.

The Movement

At the heart of this model lies a solar movement. Resistant to magnetic fields and vibrations, it delivers reliable performance across the hands, date function, subdial, and all other features. This Japanese Tough Solar in-house mechanism runs with a precision of ±15 seconds per month (without signal calibration or mobile link). It promises a power reserve of approximately 5 months in the dark and 18 months in total darkness during storage. To conserve energy, the power-saving mode activates automatically and the hands come to a stop.

The Bracelet

This stunning bracelet is a perfect complement to the watch. It is crafted from a special titanium alloy - DAT55G - that is both exceptionally hard and remarkably malleable. Its brushed and polished links contour naturally to the wrist for a comfortable, secure fit. The black colorway pairs effortlessly with both dressed-up and casual looks. Lightweight and pleasant to wear, it makes for an excellent everyday companion. It also features an adjustable triple-lock deployment clasp operated by a simple button press, accommodating wrist sizes from 150 to 205 mm.

Water Resistance

This model offers water resistance rated at 20 atmospheres, or 200 meters - making it a true diver's companion. It's engineered for freediving and can handle everything from showers and baths to sport swimming and snorkeling without breaking a sweat. You can even use a high-pressure washer with this watch on your wrist. However, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. As always, avoid operating the crown or pushers while submerged to keep the movement in perfect shape.
