Product Details
Description
The Casio G-Shock GBM-2100A-8BER is part of the G-STEEL 2100 series, combining robust shock resistance with refined design. The distinctive stainless steel case in the iconic octagonal style is crafted through forging, milling and polishing, with a circular hairline finish on the top surface and a mirror-polished shine on the sides. The dial in a bright yellow-gold tone with black-accented indices uses vapour deposition technology to achieve a metallic texture. Hands and indices feature a luminous coating, ensuring excellent legibility in the dark.
Both the case and strap are made from eco-conscious bio-based resin. The Tough Solar system charges the watch via light, ensuring reliable power at all times. Via Bluetooth, the watch connects to the CASIO WATCHES app and synchronises the time automatically. With water resistance to 20 bar and shock resistance, the GBM-2100A-8BER is equally suited to sports activities and everyday business wear.
