A flagship full-metal G-SHOCK model.
The popular octagonal 2100 series
finally sees the arrival of its all-analog, full-metal flagship: the GMC-B2100.
Combining a mechanical-looking premium feel with practicality, this is a masterpiece worthy of rounding out G-SHOCK's 40th anniversary.
🔹What Is the GMC-B2100? Full Metal Meets Analog

Based on the popular GA-2100, nicknamed CasiOak, the GMC-B2100
is a top-tier model with a full-metal case, solar charging, and Bluetooth connectivity.
Unlike the earlier GM-B2100 analog-digital model,
this model is entirely analog; with reduced thickness,
it delivers an intricately crafted metal face approaching that of a luxury watch.
🔹Design: An Octagonal Metal Face

The top bezel receives a hairline finish,
while polished, mirror-finished surfaces on the sides and lugs
bring out the metal's three-dimensional character.
The hour markers receive silver vapor deposition,
balancing legibility with a premium feel.
Slim, refined hands also create an urban impression.
Easy to match with business or casual outfits, its monochrome design is
a true fusion of metal and black.
🔹Functions: Bluetooth and Tough Solar Together

Alongside G-SHOCK's traditional toughness, it includes
Bluetooth Mobile Link.
Connecting to the CASIO WATCHES smartphone app
enables automatic time adjustment, World Time settings, timer synchronization, and other functions.
It also uses Tough Solar, which charges from light,
combining freedom from battery replacement with accurate timekeeping.
🔹The Commitment to Quality at Yamagata Casio
Manufacturing takes place at Yamagata Casio, which handles the premium lines.
From mirror polishing and blasting to IP coating,
this mother factory combines craftsmanship with precise robotic machining.
Its finishing quality truly deserves to be called the pinnacle of metal G-SHOCK.
Yamagata Casio primarily manufactures premium lines, including 5000 series models such as the GMW-B5000D.
