Introducing the latest G-SQUAD additions to the GBA-900 Series of Smartphone Link timepieces.

This model can measure distance using an accelerometer while linked with the GPS function of a smartphone via Bluetooth.

Once you take measurements with a smartphone, the next time you will be able to measure distance with the watch alone.

Distance and running time measurements are used to calculate your pace, and an auto lap feature automatically records the time it takes to cover a specific distance.
You can also check your activity history by linking with an app running on your smartphone. The app also helps to simplify the configuration of watch settings and training management.

A 5-level exercise intensity graph and a daily goal attainment rate help keep you motivated.

Super Illuminator face illumination keeps face information easy to read, even in the dark. The band’s soft urethane material improves the fit to the wrist, and vent holes improve breathability. This watch connects with your phone via Bluetooth® to support auto time adjustment, phone notifications, step tracking, and other functions throughout the day. Battery life is approximately two years between replacements.

Watches.com has been shipping worldwide since 1999 and we ship internationally daily. Most orders are processed and shipped out by 5pm (MST) Monday through Friday on regular business days. Payment/fraud verification is typically instantaneous, but in some instances may take up to 48 hours. Orders placed/received after 12:00pm (MST) will be processed the next business day. Please be aware that UPS does not deliver on weekends.

Because customs fees vary by country, we do not collect duties during checkout. If duties are due, your customs agency will let you know when the package arrives in your country. It is your responsibility to pay these fees to your country.

Once items are shipped, liability is covered by the terms of the carrier. We will ship to the address specified by the customer. If you did not provide us with an accurate address, neither Watches.com, nor the shipping carrier can be held responsible for the loss of an item. Please double check your shipping address.

Note:  Per Casio's policy, Casio and G-Shock watches are not eligible for International Shipping.  Any international order containing a Casio or G-Shock watch will be cancelled and all monies refunded.

We could all use some extra time. If your new, unworn item is not 100% to your satisfaction, you have 30 days from the original ship date to return it. To be eligible for a return, your item must be unused, unworn and in the same condition that you received it (including any protective stickers still on it). It must also be in the original packaging. More details can be found on our Returns page.  **Unfortunately Mystery watches are final sale and only eligible for return for store credit; a small restocking fee applies to these returns.
