Introducing the GA-B001 line of G-SHOCK watches — Featuring a new toughness-driven design and Smartphone Link functionality Bold color schemes take you from stylish urban streets. More than just fashion, these timepieces also deliver full functionality. Sync with your smartphone via Bluetooth® and tap into the dedicated app to access the functions you need. The GA-B001 line features an innovative construction, with two separate top and bottom bezel components that connect at the 9 and 3 o’clock positions. This ingenuity is complemented by a meticulous attention to detail, with index markings and a uniquely shaped LCD designed as never before on a G-SHOCK. Choose from all black, either black or turquoise blue in translucent gradated color, or the newest addition, red.

Innovative construction with a distinctive design:
Representation of the digital worldview

A new approach to toughness-driven design delivers an integrated bezel and band construction, while Smartphone Link puts full functionality right at your fingertips. The dial evokes a gateway to virtual reality worlds with an iconic layout featuring a distinctive inset dial. With engaging app-linked display features and more, the watch integrates the digital worldview with analogue expressivity.

Ingenuity in exterior design:

Integration of the bezel and band

A new approach to construction employs four fine-resin materials to secure the integrated bezel and band components. An enhanced fit on the wrist is achieved by moving the band’s curved support points up close to the case. In addition, attaching the glass with adhesive keeps the lug portion more compact. This design gives the bezel and band of the watch a more sharply defined profile. Also, the two-tone light button at the 2 o’clock position (on the GA-B001G-1A and GA-B001G-2A) shows the watch’s meticulous passion for detail with its iconic molded design.

Dial design evoking a gateway to virtual reality worlds


The entire dial is constructed with innovative molding, featuring a geometric inset dial evoking a security lock from the not-too-distant future, a round index with a rivet motif inspired by a corridor on a spacecraft, and a uniquely shaped LCD with a digital display. With its brilliantly distinctive design, the watch captures the spirit of a gateway leading into a virtual reality world.


Cyber colors with "near-future" vibes

The GA-B001G-1A and GA-B001G-2A models feature gradated translucent materials that call to mind virtual reality worlds. Their construction makes the inner case visible through inorganic-feeling colours. The GA-B001-4A sports a brand new shade of red. Oversaturated and high-impact, the hue expresses the “near-future” vibe of a virtual reality world. The GA-B001-1A features a uniform colour scheme with black all around.


Carbon Core Guard structure, both strong and light

The shock-resistant structure unique to G-SHOCK protects the module, with a carbon fibre-reinforced resin case offering strength, lightness, and excellent weather resistance.
