FAQs
How do I know if my watch is sufficiently charged?
The watch features a battery level indicator. If the indicator shows 'L' (Low) or 'M' (Medium), expose the watch to light. If it shows 'H' (High), the charge is sufficient for normal operation.
Can I use the watch without connecting it to a smartphone?
Yes, the core timekeeping functions, stopwatch, timer, alarm, and world time features can all be used independently without smartphone connection. However, the smartphone link provides enhanced accuracy and easier settings adjustments.
Is the Sapphire Crystal truly scratch-proof?
Sapphire Crystal is highly scratch-resistant, second only to diamond in hardness. While extremely difficult to scratch under normal use, it is not entirely scratch-proof and can still be damaged by harder materials or extreme impact.
What is the purpose of the 'Smart Access Technology'?
Smart Access Technology uses an electronic crown to provide intuitive and quick control over the watch's various functions. By rotating and pressing the crown, you can easily switch between modes and adjust settings, streamlining operation.
How often do I need to replace the battery in this solar-powered watch?
Under normal use and with regular exposure to light, the solar-powered system is designed to provide years of reliable operation without requiring battery replacement. The rechargeable battery inside has a very long lifespan.
Can I take this watch scuba diving?
With 200-meter water resistance, this watch is suitable for recreational scuba diving. However, it is crucial not to operate the watch's crown or buttons while underwater, as this can compromise the water seal.
What is the benefit of the 'Core Guard Structure'?
The Core Guard Structure utilizes a combination of resin and stainless steel components to absorb shocks and protect the internal module from impacts, enhancing the watch's overall durability and shock resistance characteristic of G-Shock timepieces.
Troubleshooting
Watch is not charging or shows low battery.
Ensure the watch face is exposed to bright light (preferably sunlight) for an extended period. Avoid covering the watch with clothing or storing it in dark places. Refer to the manual for specific charging duration guidelines under different light intensities.
Bluetooth connection to smartphone fails or is unstable.
First, ensure Bluetooth is enabled on your smartphone and the 'G-SHOCK Connected' app is open. Check if the watch's Bluetooth mode is active (often indicated by a 'BT' or similar icon). Try restarting both your phone and the watch. If issues persist, unpair the watch from your phone's Bluetooth settings and re-pair it through the app.
Time is incorrect despite being paired with a smartphone.
Confirm that your smartphone's time and date settings are correct and set to automatic. Within the 'G-SHOCK Connected' app, manually initiate a time synchronization. Also, check the watch's home city setting to ensure it matches your current location or desired primary time zone.
Phone Finder feature is not working.
Verify that your watch is currently connected to your smartphone via Bluetooth. The 'G-SHOCK Connected' app must be running in the background on your phone, and the phone should be within the effective communication range of the watch. Ensure your phone's volume is not muted.

Setup, Compatibility & Care
Initial Setup
- Charge the Watch: Upon first use, ensure the watch is adequately charged by exposing its face to a bright light source (sunlight or strong artificial light) for several hours. This activates the solar power system.
- Pair with Smartphone (Optional but Recommended): Download the 'G-SHOCK Connected' app from your smartphone's app store. Enable Bluetooth on your phone. Follow the in-app instructions to pair your watch, typically involving holding down a specific watch button to activate pairing mode.
- Time Synchronization: Once paired, the watch will automatically synchronize its time with your smartphone, ensuring atomic-level accuracy.
Compatibility
- Smartphones: The Bluetooth Smartphone Link function is compatible with select iOS and Android devices. Refer to the G-SHOCK Connected app's compatibility section for the most up-to-date list of supported operating systems and phone models.
Care and Maintenance
- Cleaning: Regularly wipe the watch case and bracelet with a soft, damp cloth to remove dirt, sweat, and moisture. For stubborn grime, a mild soap solution can be used, ensuring to rinse thoroughly with fresh water afterward.
- Water Resistance: The watch is water-resistant to 200 meters. This means it is suitable for recreational scuba diving, but avoid operating the crown or buttons underwater unless the watch is specifically designed for such operation (which the GST-B100D-1AER is not for crown operation). After exposure to saltwater, rinse the watch with fresh water.
- Charging: To maintain optimal battery performance, avoid storing the watch in dark places for prolonged periods. Regular exposure to light is essential for the solar charging system.
- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect its functionality and longevity.
- Crown Lock: Utilize the crown button lock feature to prevent accidental operation during activities.
