## Description

From G-SHOCK, the watch that always strives for toughness, the first G-STEEL lineup models to offer chronograph performance in analog format. Thought all the dials of these models are analog, they still boast G-SHOCK level shock resistance. The dial at 9 o'clock has a multi-functional rotating disk that is cut to resemble the thick blades of a jet engine. Rotation of the blades reveals red coloring behind the disk, and this change in color is used to indicate the battery level and the alarm on/off setting. The blades also rotate in the Timekeeping and Stopwatch modes to with the passage of time. A new layer guard structure houses resin cushioning parts inside the case, for a more elegant design and a better fit to the wrist. High density mounting technology makes it possible to create a module that is smaller and thinner, which also contributes to a better fit. These watches are equipped with Bluetooth that lets them connect with a smartphone at the press of a button, and acquire time information from an internet time server. The result is accurate timekeeping no matter where in the world you happen to be. Other functions include Tough Solar in combination with CASIO original power saving technology for a stable supply of power, high brightness LED light illumination, and dual dial World Time.

## Questions & Answers

**Q: Is there a international warranty card? Thx.**
A: WARRANTY CARD IS VALID ONLY FOR SERVICE IN THE COUNTRY OF PURCHASE.

**Q: What exactly does the app do for the watch besides set the time?**
A: The app primarily syncs the time to your phone but also offers a secondary time zone for travelers as well as alarm and timer but obviously your phone already has those features. The only other thing the app has is the guide that is the instructions for use document. So essentially you are correct, the app mostly is making sure time is exact by syncing with your phone but even so you have to push the red button to update it for daylight saving time changes.

**Q: Is this watch made in japan? just to confirm before i place my order.  thank you.**
A: the watch is cased in China

**Q: What does “Battery life: 5 months” means?**
A: This is a solar power watch, if left in a drawer for example it should have power reserve lasting that long without exposure to light
