Product Information

Metal-clad daring meets sophisticated gleam in a GBM-2100 that delivers Smartphone Link via Bluetooth® and Tough Solar charging system, all in a meticulously finished metal design with iconic octagonal bezel.

Choose from a basic black dial or metallic vapor deposition in blue or green, each complemented by a band made of environmentally responsible bio-based resin.

Welcome to a whole new level of metal-clad 2100 functionality — tough construction and stylish design in a timepiece that takes you from casual settings to business meetings without a thought.

Accentuating an iconic form
A stainless-steel bezel and inner case made with glass fibre-reinforced resin safeguards the module. Inheriting the design concept of the very first G-SHOCK with its iconic octagonal form, the bezel is crafted in a meticulous process of forging, cutting, and polishing. A circular hairline finish applied to the top surface and a mirror polish on the sides give the bezel a beautiful gleam.

High-contrast face for readability and beauty
The dial incorporates an oblong grid pattern applied with transparent printing and a circular hairline finish. This combination accentuates the dimensionality of the LCD and inset dial, lending a modern touch to the face. The blue and green models feature metallic textures achieved with vapour deposition. Vapour deposition and a phosphorescent finish are also applied to the three-dimensional index marks to offer enhanced watch readability in the dark.

Solar-powered timekeeping with Bluetooth® for enhanced accuracy and reliability
The watches come with Smartphone Link and Tough Solar, while still retaining the slim profile for which the 2100 line is known. These functions eliminate the trouble of time setting and regular battery replacement, offering even greater convenience for everyday use. Combining stylish design and practicality, this lineup of lifestyle watches is tailored to everyday needs, but adds a special flair.

Attention to materials: Bio-based resin
Key resin components of the case and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.

Super Illuminator (high-brightness double LED light) for maintaining watch readability in the dark
