Review: コストパフォーマンスに優れています、、最初の電池交換ではパッキンも交換した方がいいみたいです。かなり傷んできたのですが、お気に入りなので同じものを買い替えました。
Review: I wanted a watch for my boyfriend that could handle anything without me having to baby it, and this one absolutely delivered. It has that classic rugged G-Shock look, but in person it looks even better — sleek, all-black, and very solid. It’s extremely durable. I’ve bumped it a few times at work and it didn’t get a single scratch. The shock resistance is no joke, and I love that it’s also magnetic-resistant and water-resistant up to 200M. My boyfriend showers, works out, or be out in the rain without worrying about it. The analog-digital combo is easy to read once you get used to it, and the backlight works great at night. It’s comfortable on the wrist despite being a larger watch, and the band feels strong and high quality. Overall, this is the kind of watch you buy once and keep for years. Reliable, tough, and stylish in a very simple way. Definitely worth it.

## Questions & Answers

**Q: Does the watch come with the box, owners manual ect?**
A: Yes, Mine did! Threw manual away along with the box. I've had several Casio's in the past but this is my favorite! I've received lots of compleme s.

**Q: I have a smaller size wrist. Is this watch going to make me look like I am wearing a microwave oven?**
A: Thanks. I will think of getting this one or the same model with the grey camo in the face (looks sharp but $40 more...???!)

**Q: which watch is it? the blacked out version or the one with red and white writing? they are not only diffrent colors but completely diffrent watches.**
A: I ordered the G-Shock Big Combination Military watch in matte black. Everything is black except for the hands which look like brushed aluminum

**Q: Does this watch has atomic time keeping?**
A: You smart alecs know what the guy meant. Just answer the question. No it does not. See how easy that was. To the original question, any casio watch that syncs to the atomic clocks will say Multi Band 6 somewhere on the face. This is a feature that they don't hide.
