Visual Audit: A Study in Monochrome Depth
Our visual audit confirms a sophisticated palette of turquoise blue, designed for the modern individual who values technical depth and a “street-savvy” profile.
- Monochromatic Turquoise Dial: A multi-layered face utilising subtly different shades of blue to highlight indices, hands, and sub-dials.
- Octagonal “CasiOak” Bezel: An iconic geometry inherited from the first-generation G-SHOCK, reimagined in a slim, modern form.
- Neobrite Luminous Hands: High-visibility hands that provide a long-term glow in the dark after only a short exposure to light.
Material Verification: Sustainable Carbon Toughness
The GA-2100-2A2ER is constructed using G-Shock’s proprietary Carbon Core Guard structure and bio-based resins to ensure lifelong durability and comfort.
- Carbon-Reinforced Resin: A high-strength, lightweight material that allows for a slimmer 11.8mm case profile without sacrificing shock resistance.
- Bio-Based Resin Band: Produced from renewable organic resources to help reduce environmental impact while maintaining skin-safe comfort.
- Mineral Glass Protection: A toughened crystal face recessed beneath the bezel to prevent scratches and impact damage.
Mechanical Functionality: The Legend of Module 5611
Beneath the turquoise dial lies the high-torque digital-analog module 5611, ensuring accurate timekeeping and a massive suite of timing utilities.
- Double LED Super Illuminator: High-intensity white lighting for both the analog dial and digital display for perfect visibility in the dark.
- 20 ATM Water Resistance: Engineered for life in the water, including professional swimming, snorkelling, and diving (200 metres).
- Hand Shift Feature: A technical utility that moves the analog hands out of the way for a clear view of digital stopwatch or alarm data.
