Which G-SHOCK fits a small wrist?

Resin, steel bezel or full metal: how much does weight change?
The resin GA-2100 weighs 51 g. Adding a stainless steel bezel makes the GM-2100 72 g, and the full-metal GMW-B5000 weighs 167 g. Custom full-metal builds also sit at the heavy end, so choose resin if you want a watch you forget you're wearing.
What band size do G-SHOCKs fit?
Casio lists the stock resin band of the GA-2100, GA-B2100, GM-2100 and GA-700 as fitting wrists from 145 to 215 mm (about 5.7 to 8.5 inches).
