Casio G-Shock G-STEEL 2100

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.

Key Features of the Casio GBM-2100A-8BER

  • Tough Solar with Bluetooth: Solar charging and automatic time synchronisation via smartphone app for precise timekeeping worldwide.
  • Shock Resistance and 20-Bar Water Resistance: Robust construction for daily use under demanding conditions.
  • Bio-Based Resin: Eco-conscious material for the case and strap, combined with a precisely crafted stainless steel bezel in the classic G-Shock octagon design.
