Reviews about G-SHOCK Classic Women GM-S2100BC-1AER (4)
The metal finish of the case, combined with the black strap, gives it a modern edge, making it a perfect match not only for athletic leggings but also for more casual outfits. It’s surprisingly slim for a G-SHOCK, so it fits perfectly on a smaller, women’s wrist without losing any of its legendary durability.

This model is the perfect proof that sporty durability can go hand in hand with feminine style—the rose gold-colored case, crafted from stainless steel, looks incredibly luxurious and striking. I really appreciate the fact that despite its smaller, typically feminine size, the watch has retained all the key features of a G-SHOCK, such as incredible shock resistance and water resistance up to 200 meters. The combination of analog hands with a digital display is very intuitive, and the bright Super Illuminator backlight makes reading the time in the dark completely hassle-free. It’s a great choice for the active woman who doesn’t want to compromise on elegance, even during demanding challenges.

It's quite large, but that's a plus—you can see everything clearly. It has an interesting design and is the perfect everyday watch.
