G-Shock introduced a new G-Steel model this week which has an elevated look, new features, a lighter, more robust construction, and is the first G-Steel watch to incorporate a front light button.

Introducing the G-Steel GSTB300S-1A, crafted in a highly durable stainless steel, carbon fiber, and resin case. The top of the 51 mm diameter x 14.5 mm thick case — including the vertically brushed bezel — as well as the caseback, screws, buckle, crown, and buttons are made of stainless steel. And the middle of the case features the latest Carbon Core Guard Structure comprised of a carbon fiber reinforced with resin that’s both lighter than past models and provides enhanced shock resistance. The total weight with the polyurethane strap is 91 grams.

A redesigned dial offers dual-digital multi-function displays to display functions such as the day, date, alarm time, city and other functions. Two large steel sword-shaped hands combined with prominent steel indices (and an Arabic numeral “12”) make determining the hour and minute at a glance effortless. The analog hands are lume-filled and each hour marker has an accompanying lume rectangle, so even if pushing the dual-LED button on the bottom of the bezel is not an option, the dial will still be readable in dim conditions. To save power, the analog second-hand moves every 10-seconds as opposed to continuously.

The Japanese-made module 5631 battery-powered quartz movement features Tough Solar Power which requires no user input. Light enters the dial and automatically recharges the battery (the battery lasts approximately 20-months). This ability to recharge itself is a great convenience and is especially useful considering the new front light is a high-luminosity double LED light, which naturally, requires a significant power draw from the battery.

Interestingly, the subdial at 6 o’clock, which was designed to visually evoke a brake disk, shows the battery status from F to E (on the left side), so you can ensure that the watch is being properly recharged. On the right side of the same subdial are the four modes the watch can be toggled between (WT – World Time mode, ST – Stopwatch mode, TR – Timer mode, AL – Alarm mode) using the pusher on the caseband at 8 o’clock.

As for functions, in addition to automatic time adjustment via Bluetooth® when paired with G-Shock Connected App, the watch features a world time setting for over 300 cities ((39 time zones + UTC) as well as 5 multi-function alarms, a countdown timer, a 1/1000th of a second stopwatch, hand retract function (hands move out of the way to provide an unobstructed view of the digital displays), and a full-auto calendar. There’s also an hourly time signal feature,

The dial is protected by a flat mineral crystal, the watch is highly resistant to shocks, water-resistant to 200 meters, has a steel caseback secured by four screws, and features a softer, more comfortable strap design with a more secure buckle that uses dual-pronged pins to prevent it from becoming loose.

There are four new G-Steel variations in total, including two with a stainless steel bracelet.

Retail as shown is $330. Learn more at G-Shock.
