Casio’s latest G-Shock Bluetooth watch brings music identification to your wrist

The G-Shock GBA-400 is the latest smartphone-connected Bluetooth watch from Casio, but instead of delivering notifications or measuring fitness levels, it’s all about music. It’s built to interact with Casio’s G’Mix app, to which it connects using Bluetooth, and uses a combination of the rotary dial and side-mounted buttons to activate several features.

Unusually, the watch can be used to listen out and identify music that’s playing around you. Twist the dial to turn the ID feature on – which is symbolized by a cool dial on the watch face – and using Soundcloud technology, the name of the song you’re trying to identify will scroll across the built-in screen. All without reaching for your phone, or bothering Siri.

The dial can also be used to adjust the volume of music playing on your phone, skip to other tracks, or change the EQ preset. Using a button on the opposite side of the phone can play or pause tracks. When the Bluetooth connection is active, it’ll keep the time on the watch up to date, even if you change time zones. If you misplace your phone, the watch can remotely sound an alarm to help find it again. Additionally, the app can control the watch. You can set up daily alarms and timers, fix the amount of time the Bluetooth connection stays active, and even how long the backlight stays lit.

All these smart features are inside a familiar G-Shock watch, which has a tough 51mm case that’s waterproof to 200 meters, shock resistant, and contains a battery that’s good for two years. The GBA-400 will be sold in four different color schemes – sporty red or blue, a muted black and silver, or a flashier black and gold model. The price for this interesting take on the smartwatch has been set at $200, and it’ll be on sale in October.

If you’re ready to pick one up, be aware the device compatibility page currently only lists iOS 7 Apple devices, and a handful of Samsung Galaxy smartphones running Android 4.3 or 4.4. This could all change before release, but make sure you check it’ll work with your phone before buying.

The tech-boosted G-Shock GA-B2100 watch is a great buy
Blue and yellow G-Shock GA-B2100 together.

It can initially be quite hard to grasp why the little Casio G-Shock GA-B2100 is such a brilliant watch. After all, it’s cheap, it’s not a sci-fi-influenced limited edition, and on the technology side, it’s not as comprehensively specced as a fitness-orientated G-Shock, let alone an Apple Watch.

Yet it’s one of my favorite G-Shock watches of recent times, and a great buy. Here’s why.
Why is it popular?
The original G-Shock GA-2100 (note the lack of the B in its name) came out in 2019 and was an instant hit. The $99 price point was just right, the analog/digital look is pure G-Shock, and it was available in various colors so it appealed to the many people who buy G-Shock watches as fashion accessories. The passing (if you squint very hard) resemblance to the Audemars Piguet’s octagonal Royal Oak luxury watch helped build its legend online too.

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.

Casio G Shock Burning Red models.

One of our favorite things about Casio’s G-Shock range of watches is the breadth of choice there is when it comes to colors and styles. We reviewed the simple black version of the GBD-200 Bluetooth fitness watch, but if that’s not bright enough for you then take a look at the new Burning Red series, which paints the GDB-200 and GBA-900 hybrid connected watches in a striking red color.
