There are many styles of G-shock of Casio, and there are many colors, which is really great for matching.
I searched on the Internet and found that the small square electronic watch is very characteristic, and the black color is easy to match. It happened that I had a friend in Japan and asked him to bring one back for me by the way. The price is very cheap, and if you use a credit card, there is a cash back. You can buy it for CNY510.
This watch is an electronic watch, and it is solar, so you don’t need to change the battery. It is waterproof to 200 meters and it is no problem at all when it is taken to swim.
