Product Details
Description
The Casio G-Shock GM-2100RW-1AER is a striking analog-digital model from the GM-2100 series, featuring a unique shimmering rainbow brick-pattern dial. This distinctive decoration is created through a combination of silver vapour deposition, laser engraving and multicolour printing — a legendary design element that pays homage to the very first G-SHOCK and shifts through various colour tones depending on the light. The robust glass-fibre reinforced resin case is crowned by a high-quality stainless steel bezel, crafted through an intricate process of forging, cutting and polishing that combines hairline and mirror finishes.
The watch offers an extensive feature set: world time across 31 time zones, a 1/100-second stopwatch, a countdown timer, five daily alarms and an hourly time signal. The dual LED light (Super Illuminator) ensures excellent legibility in the dark, complemented by Neobrite luminous material. The strap is made from bio-based resin. The watch is shock-resistant and water-resistant to 20 bar — a reliable companion for any adventure.
