Casio GST-B1000 Rubber-Strap G-Steel Watches Appear in Clear New Renders
Fresh high-resolution renders of Casio’s upcoming G-Shock G-Steel GST-B1000 rubber-strap models have surfaced, giving watch fans a much clearer look at what to expect from the new lineup. The images show two versions: the black GST-B1000-1A and the blue GST-B1000-2A, both bringing a sporty resin strap design to the G-Steel family.
The latest renders reveal far more detail than the earlier leaked images, especially around the dial, caseback, and color-matched design elements. While the overall layout stays familiar for anyone who has followed the GST-B1000 series, these new models appear to focus on a lighter, more wearable build without losing the tough identity that defines the G-Shock name.
The dial design is packed with information, staying true to the functional style of the G-Steel range. On the left side, there is a day-of-the-week subdial that also includes ON/OFF markings and indicators for alarm, timer, and stopwatch functions. On the right, a 24-hour subdial adds another layer of utility, while the date window sits near the 5 o’clock position.
Behind the G-Shock logo, Casio has added a ribbed horizontal texture that gives the face a more technical, layered look. It is a busy dial, but that is part of the appeal for many G-Shock fans who prefer a watch that feels tool-like and feature-rich.
One interesting detail separates the two color options. The blue GST-B1000-2A uses a white date wheel, making the date easier to read at a glance. The black GST-B1000-1A, on the other hand, keeps a black date wheel for a more seamless, stealthy appearance. It is a small design decision, but it could make a noticeable difference in daily use, especially for those who value quick readability.
The caseback also confirms several important specifications. The watches feature a stainless steel backplate with Carbon Core Guard branding, Tough Solar markings, module number 5748, and 20-bar water resistance. That means these models should offer the durability and everyday practicality expected from a modern G-Shock, including solar-powered operation and strong protection against water exposure.
Casio has also added colored resin accents on the back of each model. The black GST-B1000-1A gets a red accent piece, while the blue GST-B1000-2A features a matching blue accent. These details are not immediately visible from the front, but they add a more premium and thoughtful finish to the overall design.
The dimensions are listed at 46.9 x 44.2 x 11.6 mm, making the new GST-B1000 rubber-strap models relatively compact for a G-Steel watch. However, the most important number may be the weight. While the bracelet version reportedly weighs around 118 grams, these rubber-strap versions drop to just 58 grams.
That dramatic weight reduction could make the GST-B1000-1A and GST-B1000-2A much more comfortable for everyday wear. For users who like the durability and look of the G-Steel series but find metal bracelet models too heavy, these upcoming resin-strap versions may be a strong alternative.
The Casio GST-B1000 rubber-strap watches are expected to be officially introduced in August. If the leaked details are accurate, they could become appealing options for buyers looking for a lighter G-Shock G-Steel watch with Tough Solar power, Carbon Core Guard construction, 20-bar water resistance, and a bold analog-digital inspired dial layout.
With clearer renders now available, the GST-B1000-1A and GST-B1000-2A look like practical, stylish additions to Casio’s expanding G-Shock G-Steel lineup. The lighter build, color-specific details, and rugged feature set may help these models stand out among upcoming G-Shock releases.
