G-Shock finally gives some attention to ‘Air’ in its Master of G series

G-Shock releases GRAVITYMASTER GR-B300, inspired by airplane cockpits

G-Shock is not known as a brand that makes watches for pilots, or anything aviation-inspired; those brands are usually Longines, IWC, or even Zenith. Generally, when you think of G-Shock, you probably imagine a mud-covered man running through the forest when it’s pouring rain, checking his watch as he splashes through puddles with a sweat-covered brow. However, the brand has surprised us all.

Following a brief break since the launch of the GR-B200 in August 2020, the GRAVITYMASTER GR-B300 has been released this year. While G-Shock expanded the Master of G series last year, celebrating the land category with Mudman, Mudmaster, and Rangeman, we can finally take to the skies and move into the “Air” category with the newest release, screaming “up, up, and away” in the process. Not only is the GRAVITYMASTER GR-B300 a celebration of aviation, but it draws serious inspiration from supersonic jets and modern aircraft with its sleek design. As aviation itself advances, so too must pilot watches and the new GRAVITYMASTER GRB-300 exemplifies this to a T.

A plane should be reliable and damn near indestructible if you’re the one riding it, so why shouldn’t watches that pay homage to aviation also feature these characteristics? The latest G-Shock GRAVITYMASTER uses carbon material similar to what you find in high-tech aircraft meaning it’s so lightweight that you’ll barely know you’re wearing it as you go about your activities. However, it’s still ridiculously strong, so it will protect the internal components of your watch.

In case you forgot that this new G-Shock GRAVITYMASTER is inspired by airplanes, the brand has put it right in your face on the dial. The striking black and white design features very large hands on the triple-layer dial, and both the hands and markers glow in the dark. Most importantly, this watch has a red-accented version to represent night lighting in airplane cockpits, and the blue-accented version represents the cockpit’s head-up display (HUD), which is what pilots see on their front window.

Technical specifications

While a dial that resembles an airplane cockpit is all well and good, you’re not in it for the fancy design (at least not completely.) So, what about those tech specs? The GRAVITYMASTER GR-B300 is equipped with Quad Sensor technology and includes a compass, altimeter/barometer, thermometer, and step counter, meaning it’s not only ideal for the skies but for the land as well.

Of course, it is made for the sky, so it comes with a Mission Log Feature that records altitude data and GPS coordinates and has a Location Indicator that shows the direction and distance to a previously recorded point. This G-Shock watch includes a rotating indicator at 9 o’clock that displays the solar power charge and alarm status, and it comes with a second time zone subdial. Other features include a day and date display, stopwatch, countdown timer, and Super Illuminator LED light.

While it’s a mouthful to list out all the features, this is what G-Shock watches are known for so lots of bells and whistles are basically a given.

How much is it and where can you buy it?

The G-Shock GRAVITYMASTER GR-B300 comes in at $300, which for all the features and the 200 meter water resistance is a total steal. You can buy them on the official G-Shock website.

Timex gives heritage chronograph a sporty summer makeover with fabric straps
Timex makes Daytona-inspired Waterbury even more affordable with fabric strap option
Timex Waterbury Heritage against white babckground

Timex has launched a sportier version of its popular Waterbury Heritage Chronograph, just months after the Daytona-inspired timepiece became a hit with budget-conscious collectors. The new Waterbury Heritage Chronograph 39mm Fabric Strap edition offers the same racing-inspired design at a more accessible $299 price point.
The updated chronograph maintains all the functional elements that made the original successful, including its rotating tachymeter bezel, sub-dials, and Daytona-inspired pushers. The 39mm stainless steel case houses a reliable Quartz Analog movement with 50-meter water resistance and mineral glass crystal protection.
Three colorway options are available: the original black and silver, black and gold, and a new racing green edition featuring black, silver, racing green, and yellow accents that nod to classic motorsport colors. The styling remains relatively minimalistic and clean for a racing chronograph, contributing to its overall appeal.
The primary difference lies in the strap configuration. Instead of the original link bracelet or leather options, all three versions now feature matching fabric straps styled to complement each colorway. These woven bands provide a more summer-ready, casual wearing experience compared to the metal bracelet.
The fabric straps offer practical advantages beyond aesthetics. They're lighter and more breathable than traditional options while maintaining security through Timex-branded buckles. As slip-through straps, the fabric covers the case back, eliminating direct metal contact with skin during hot weather conditions.
The strap change significantly alters the watch's presentation, making it considerably more casual while maintaining the chronograph's racing heritage. The 13.5mm case thickness remains unchanged, preserving the watch's proportional balance.
This fabric strap edition represents Timex's strategy of making popular designs even more accessible. While the leather strap option maintains the $299 price point, it lacks the breathability and casual appeal of the fabric alternative.
The updated chronograph continues Timex's tradition of offering Swiss-inspired designs at American prices. The Daytona-like aesthetic combined with reliable quartz movement provides an entry point into racing chronographs without the premium price tag.
All three versions are available immediately through the brand's website. The $50 price reduction from the bracelet version makes this already affordable timepiece even more attractive to budget-conscious enthusiasts.

Why the Parmigiani Fleurier PF070 deserves every watch lover’s attention
Parmigiani Fleurier Tonda PF Chronograph 40mm

In the watch business, where larger players like Rolex and Omega control attention, independent Swiss makers find it hard to get noticed. But often, smaller companies build movements that exceed their well-known rivals in technical quality. For example, Parmigiani Fleurier's new PF070 chronograph caliber is a 5Hz movement that stands out, and watch experts should be watching.
Many watch fans can list Rolex's newest items, but fewer know about the technical work operating in Parmigiani Fleurier's Tonda PF Chronograph. The PF070 shows what makes independent watchmaking different: its careful engineering, new answers, and specifications that could cause other makers to envy it.

The integrated movement advantage: Why PF070 stands apart

Casio brings back its impossibly small ring watch
Second chance: Casio's miniature ring watch returns to American market
Casio Ring Watch CRW001-1

Casio announced the US restock of its Ring Watch CRW001-1 on July 1st, bringing back the small timepiece that sold out quickly after it came out in America in late 2024. The restock follows successful lottery sales in the UK and Japan, showing that people around the world want this digital watch that goes on a finger.
The Ring Watch CRW001-1 shows Casio's bold way of looking at wearable technology—it shrinks standard digital watch functions into a ring that measures only 25.2mm across and weighs 16 grams. Even though it is small, the timepiece keeps necessary features, including support for two time zones, a stopwatch that measures 1/100th of a second, and hourly flash alerts.
Casio US confirmed the July 1st restock on Instagram, saying the watch would only be available through the brand's online store, not in physical shops. Compared to the lottery systems in other places, American customers will buy the watch in the order they arrive—this might cause a lot of competition among people who collect things and those who like technology.
The small digital screen has a backlight so you can see it in different light. The stainless steel build makes it sturdy, even though it is small. The ring fits size 22 fingers (US 10.5, EU U), and you can adjust it down to size 19 (19mm inner diameter) or size 16 (18mm inner diameter).
The engineering needed to put normal digital watch parts into a ring shape shows how well they made it. The 1/100th second stopwatch is as exact as bigger Casio watches. Travelers who want to check the time without others knowing will like the two-time zone feature.
Casio did not say the exact restock time but told interested customers to sign up for email notifications about when it would be ready. That way may help manage the internet traffic while making sure serious buyers learn about buying chances in time.
The Ring Watch's appeal shows more people are interested in other types of wearable devices, not just ones worn on the wrist. Casio's good result with this unusual approach shows that people want new watch designs that question common ideas about what a watch should look like.
The quick sellout after the US launch, along with international lottery systems, suggests that collectors are very interested and that the watch might sell for more later. Casio has not said anything about more restocks in other places after the July 1st US availability, keeping the watch special.
This restock gives American buyers a second chance to get one of the most noticeable wearable technology releases of the year, bringing together Casio's history with digital watches and its push to make things very small.
