Casio’s New G-Shock GRAVITYMASTER Can Fix Its Own Accuracy Mid-Flight

A watch that survives a hard knock is nothing new for G-Shock. A watch that survives the knock and then quietly corrects the timekeeping error that knock caused is a different story altogether. That is exactly what Casio has built into the new GWR-B3000, the latest addition to the GRAVITYMASTER family within G-Shock’s Master of G Air lineup.

Casio officially unveiled the GWR-B3000 on June 4, 2026, and it is now rolling out internationally through the G-Shock global site. The watch was developed around a single idea: “Supersonic.” Casio’s designers wanted a timepiece that echoes what happens when a jet breaks the sound barrier, translated into a case and movement engineered to hold precision timekeeping under genuine cockpit stress.

What Makes the GWR-B3000 Different

At the center of the watch sits a newly developed movement Casio calls TOUGH MVT.2 (Tough Movement 2). If you have not come across the term before, think of it as the watch’s engine: the mechanical and electronic system that keeps the hands moving and the time accurate. This second-generation version adds two features that were not available on earlier GRAVITYMASTER models.

The first is auto hand home position correction with shock detection. In plain terms, the watch constantly checks whether an impact has knocked its hands out of alignment, and corrects them automatically the moment it detects a strong jolt, rather than waiting for its usual scheduled correction cycle. The second is magnetic field detection, which pauses hand movement the instant the watch senses a strong magnetic field nearby, then resumes accurate timekeeping once the interference clears. Cockpits are full of instruments that generate exactly this kind of interference, so the feature has an obvious real-world use case beyond just pilots.

Holding all of this together is a dual hollow case structure, the latest version of the shock-absorbing design G-Shock has used since its very first model. The inner case is made from carbon fibre-reinforced resin for strength without added weight, while the outer case combines stainless-steel protectors with resin shock absorbers. Casio says the entire shape was worked out using topology optimisation, a computer-aided engineering process that runs repeated simulations to find the most efficient structure for absorbing impact, centrifugal force, and vibration at once.

Built to Be Read at a Glance

Pilots do not get the luxury of squinting at a dial, and the GWR-B3000’s design reflects that. The dial uses a newly developed dark black finish with microfabricated surface texturing that cuts down glare in direct sunlight, paired with an in-dial solar system where the light-collecting cells sit inside the smaller sub-dials rather than spread across the whole face. This lets Casio keep a deep, opaque dial colour while still powering the watch entirely through Tough Solar charging.

Functionally, the watch offers dual-dial world time, showing two cities simultaneously along with one-touch access to UTC. It also includes a flight log function that syncs with the Casio Watches smartphone app: pressing a button on the watch records the current time and GPS position, which then shows up on a map inside the app for tracking departure and arrival details.

Other everyday specifications include 200-metre water resistance, MULTIBAND 6 radio-controlled time sync, Bluetooth smartphone linking, a stopwatch, a countdown timer, a daily alarm, and Casio’s Super Illuminator LED backlight. The crystal is sapphire, treated with an anti-reflective coating for extra clarity.

GWR-B3000 Specifications

Price and India Availability

Casio has confirmed Japanese pricing of ¥110,000, ¥126,500, and ¥137,500 across the three launch colours. At current exchange rates, that works out to roughly ₹64,500 to ₹80,800, though this is only an approximate conversion and does not account for import duty or local taxes once the watch reaches Indian retail. G-Shock UK already lists the trio from about £750 to £870, reinforcing that this is a premium-tier GRAVITYMASTER rather than an entry-level one. Official India pricing has not been announced yet, and the watch is currently rolling out through G-Shock’s international and Asian markets first.

If you want a GRAVITYMASTER on your wrist right now rather than waiting on the India launch timeline, the current-generation GR-B300 series is already selling in the country and shares several of the same aviation-inspired design cues, including the Carbon Core Guard structure, Bluetooth flight log, and dual-time display.

Should You Wait for It

The GWR-B3000 is aimed squarely at buyers who already understand what they want from a Master of G watch: genuine toughness credentials backed by real engineering, not just a rugged look. The self-correcting movement and magnetic field detection are the kind of upgrades that matter more the harder you actually use the watch, whether that is in an aircraft cockpit or just a demanding outdoor job. Casual buyers who mainly want the aviation styling without the extra engineering can still get most of that experience from the GR-B300 series at a noticeably lower price today.

For serious G-Shock collectors and aviation watch enthusiasts, though, the GWR-B3000 looks like the new benchmark in the GRAVITYMASTER line, and it is worth tracking as it makes its way toward Indian retail shelves.
