The longer you have worn square G-SHOCKs, the more you may find yourself curious about the G-SQUAD series.
These training-focused G-SHOCKs can transform your strength training and running.
Although my reviews have mainly focused on squares, readers have begun asking which G-SQUAD they should choose.
So this time, I researched and compiled the history of G-SQUAD models in detail.
The conclusion: the GBD-200 series is the best choice for a first purchase.
Thin, light, and strong in smartphone connectivity, it remains a popular, highly refined choice in 2025.
This article will help you find a G-SQUAD that suits you without regrets.
What Is G-SQUAD? Features Across the Series
G-SQUAD is a G-SHOCK offshoot with enhanced fitness and sports functions.

Retaining G-SHOCK durability, it is a line that adds sports-oriented convenience.
