New G-Shock Mudmaster gets added carbon strength, step tracking, and Bluetooth

Casio is ready to launch the latest Mudmaster GG-B100 watch, the second to use its new Carbon Core Guard structural technology, previously seen on the 2019 Gravitymaster watch. The Mudmaster has also been given a high-tech internal makeover compared to previous models.

The Carbon Core Guard name refers to the new structure that forms the inner body of the new Mudmaster. Like a racing car, the Mudmaster has a monocoque made from carbon composite, which is light and so strong, that the buttons no longer need external guards. This slims down the Mudmaster’s shape, making it more wearable. Stainless steel is used for the case back along with carbon-fiber-reinforced resin for impact resistance, plus there are filters behind each button to keep dust and dirt out. Like all G-Shock watches, it’s waterproof to 200 meters, shock proof, vibration resistant, and low-temperature resistant, too.

Inside the GG-B100 are a selection of sensors including a compass, a barometer, a thermometer, and a new addition for the 2019 model — a 3-axis accelerometer that counts steps. Casio introduced step tracking on G-Shocks in 2018 with the GBA-800, and it appears the functionality will be repeated here. This means the Mudmaster won’t be for serious fitness addicts, and instead simply provide step count and calorie burn data.

This will all be synced to your phone using Bluetooth, another first for the Mudmaster range. The Casio Connected app is excellent, and our experience with using it has been very positive. Here, it will keep a log of your activity, plus you will be able to adjust the local and world time, along with more outdoor-related features like GPS and recording altitude data. The Mudmaster is a tough watch for anyone who enjoys outdoor pursuits, and the dust, dirt, and water resistance ensures it will continue working regardless of how messy those outdoor activities get.

Digital Trends wore the new GG-B100 watch during the Baselworld 2019 watch show and found it to be lighter and more comfortable to wear than previous Mudmasters. Step count shows up on the digital readout at the press of a button, so you don’t have to look at the app, and the exposed carbon fiber bezel adds visual style which is still in keeping with the Mudmaster’s tank-like looks.

The Mudmaster GG-B100 will come in black, orange, or khaki with a matching resin band, and the battery will last for two years. Casio will release the watch in the U.S. for $350 and in the U.K. for 325 British pounds, with the U.K. release set for August 1.

Casio adds Bluetooth and solar to the hugely popular GA-2100
Casio G Shock GA-B2100 in blue.

Don’t brush the new G-Shock GA-B2100 aside as just a collection of new colors, as this is a major update to  the highly popular octagonal GA-2100 watch. Casio has added desirable tech in the form of Bluetooth connectivity and solar charging to give it high-tech appeal, and we predict that's going to put this watch on a lot of wrists.

The Bluetooth connectivity enables the watch to sync with the Casio Watches app, where adjusting the time happens automatically and you can set alarms and timers too. It’s also simple to add a location for the world time, plus there’s a phone finder feature too. While the GA-B2100 isn’t going to challenge the Apple Watch for functionality, it does make using simple features easier and faster.

G-Shock’s red-and-gold MR-G watch makes a strong statement

Luxury smartwatches aren’t especially common, but if you are a fan of a luxury connected watch, there are more options, especially if you consider Casio’s G-Shock range. The company has released two new entries in its MR-G lineup, the MRG-B5000B and the MRG-B2000B.

Unlike the all-digital B5000, the MRG-B2000B. is an analog watch, but it still has a Bluetooth connection to make setting up and using common features a little easier than just with the buttons. I’ve been wearing the watch with its hand-finished titanium case, and boy, does it make a statement.
Luxury materials, tough features
The MRG-2000B is based on the MTG-B2000. The differences are in the materials used, the module inside the watch, and the way it’s built. G-Shock MR-G watches are built by hand at Casio’s factory in Yamagata, Japan, and assembled by the company’s most qualified engineers. The module used is functionally the same as the MT-G model's, but it's made with gold-plated retainer plates to reduce electrical resistance.

What makes MR-G so special?
Although Casio is best known for tough watches that won’t break the bank, Casio also has decades of watchmaking experience, and it showcases its talents most effectively in its highly exclusive MR-G family of watches. These models, its most luxurious, are assembled by hand on Casio’s Premium Production Line located in the Yamagata factory in Japan, where only the company’s most experienced, specially certified technicians work on the top MT-G and MR-G models.

The square G-Shock is one of the most popular models, having been around since the G-Shock brand first started in the early 1980s, and bringing it to the luxury MR-G range is going to see a lot of people reaching for their wallets. What makes it so special? It’s the first time the classic, beloved square G-Shock has been given the MR-G treatment, with most other MR-G models over the past few years featuring an analog dial. There's a huge section of an already large fan base waiting for this.
