– GST-B1000-1A and GST-B1000-2A swap to smooth rubber straps, reducing weight to about 70–80 g (from 118 g) while keeping the 46.9 × 44.2 × 11.6 mm case.
– Two colorways: 1A with black dial, 2A with a light blue dial and a brick-pattern dial texture continues.
– Expected launch window July–August 2026; pricing around $350–$370, lower than the IP-coated BD variants.
Renders of two more unannounced Casio G-Steel watches have just surfaced
Renders of two more unannounced Casio G-Steel watches have just surfaced, and they take the GST-B1000 family in a somewhat unexpected direction. The GST-B1000-1A and GST-B1000-2A — note the absent “D” suffix — swap the cast-link bracelet for a smooth rubber strap, and are expected to arrive no earlier than July-August 2026. The source is Casioblog, which previously broke the GST-B1000BD-1A and BD-2A ahead of their mid-summer reveal. All these new renders follow a similar pattern, meaning Casio may be planning a bigger GST-B1000 refresh across the same window.
Weight and dimensions noted in the early renders
The most tangible change is weight. The strap variants are expected to weigh around 70-80 grams, versus 118 grams for the bracelet-equipped GST-B1000D. This in itself is a pretty substantial drop for a steel-cased watch. As expected, case dimensions will identical at 46.9 × 44.2 × 11.6 mm. Two colorways show up in the renders: the GST-B1000-1A with a black dial, while the GST-B1000-2A gets a light blue dial. It’s not a typical blue shade either — it is way lighter in tone than the deep blue on the previously leaked BD-2A. The brick-pattern dial texture is going nowhere as well.
Bracelet replacement and strap texture details
The source describes the strap is described as “smooth-surfaced”, which is quite different from the textured inserts seen on older G-Steel strap models. Standard rubber is the most likely material, with bio-rubber also plausible; silicone appears to be less probable per Casioblog. Feature-wise, we can expect the same loadout as the rest of the lineup: Bluetooth, solar charging, 30-minute stopwatch, timer, daily alarm, Super Illuminator LED, and 200 m water resistance. Pricing is estimated at $350-370, which is a step below the ~$450 projected for the IP-coated BD variants.
