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.

IWC debuts Ceralume technology that glows in the dark
IWC Ceralume technology

IWC recently revealed "Ceralume," a luminous ceramic technology (hence the name that sounds like a celebrity couple mashup) and the inaugural watch that wears it. The Ceralume IWC Pilot's Watch Chronograph 41 is the brand's first entirely luminescent ceramic watch, combining the scratch resistance of the material with a glow-in-the-dark luminous effect. Like a watch straight out of Ghostbusters, the case, dial, and strap all illuminate, adding to the otherworldly look. It's got us feeling all kinds of early-aughts nostalgia for those plastic stars that we used to stick on our roof, though this new technology won't do any damage to your wall paint.
What is Super-LumiNova, and how does IWC use it?

For several years, luminescent material has played a crucial role in watchmaking, though that's putting it lightly. That's exemplified in just about every new watch introduction these days, with almost every single one featuring a "Super-LumiNova" dial. Super-LumiNova itself was created by Swiss firm RC Tritec, and according to IWC, it's an advanced ceramic material that accumulates light energy from natural and artificial sources, holds it temporarily, and then releases it as illumination. This process can be repeated over and over again without the material losing its ability to store light. IWC debuted the first watch to feature a black zirconium oxide ceramic case in 1986, followed by a brown silicon nitride and a black boron carbide, known for being exceptionally hard. Thus, ceramic cases have become a fundamental part of IWC.

This year marks the 100th anniversary of Citizen watches, and what better way to commemorate the momentous occasion than with a limited edition capsule collection? It's basically the cake and candles of the watch industry. The Japanese brand has unveiled five models that draw inspiration from the rocks and minerals that formed the Earth several million years ago in a geological evolution.
Citizen watches: The Layers of Time collection

Each of the 5 Citizen watches features an Eco-Drive solar mechanism, with transparent dials and a very noticeable special ink developed along with the Fujifilm Corporation that gives them a surprisingly extraterrestrial vibe despite the fact that they represent our own planet. The Layers of Time collection takes inspiration in its design from geological formations and the natural beauty of the Earth's layers, giving rise to the organic patterns and textures you would find in rocks, minerals, and fossils.

The Citizen Attesa Layers of Time Eco-Drive Satellite Wave GPS CC4057-60E features a case and bracelet made from incredibly durable Super Titanium alloy, made even better with a black Duratect finish. It's one of the more beastly watches in the new collection as its case measures 44.6mm in diameter and 15.4mm in thickness, and it's water resistant up to 100 meters. This watch has a bezel adorned with a gradient finish, echoing the colors in the dial, and it's powered by the Caliber F950 Eco-Drive movement, famous for its self-sustaining capabilities in any light.
