Setup
Initial Activation and Time Synchronization
Your ETT Eco Tech Time watch is designed for ease of use. Upon first exposure to light, the watch will activate and attempt to receive the DCF 77 radio signal. In most cases, the watch will automatically set the correct time and date for Central European Time (CET).
- Unboxing: Carefully remove the watch from its packaging.
- Light Exposure: Place the watch in a well-lit area, preferably near a window, to ensure it receives sufficient light for charging and signal reception. Avoid placing it near electronic devices that might interfere with the radio signal.
- Automatic Synchronization: The watch will automatically attempt to receive the DCF 77 signal, typically overnight. Once synchronized, the time and date will be accurately set.

Operating Instructions
Display Modes
The watch features an LCD screen that can display various information. Use the buttons on the side of the watch to cycle through the display modes:
- Date: Displays the current date.
- Day: Displays the current day of the week.
- Second: Displays the current second count.
- Signal Reception: Indicates the strength or status of the radio signal reception.
Automatic Time Adjustment
The watch automatically adjusts to daylight saving time (summer time) and standard time (winter time) based on the received radio signal. No manual adjustment is required for these changes.
Low Energy Display and Sleep Function
To conserve energy, the watch may enter a low energy display mode or a sleep function when stored in darkness for an extended period. The watch will resume normal operation and synchronize time once exposed to light again.
Solar Drive Technology
Your ETT Eco Tech Time watch is equipped with Solar Drive technology, meaning it is powered by light. A solar cell under the dial converts both natural and artificial light into electrical energy, which is then stored in a rechargeable battery. This eliminates the need for conventional battery replacements.
- Charging: Ensure the watch is regularly exposed to light to maintain its charge.
- Overcharge Protection: The watch features an integrated overcharge protection mechanism to prevent damage to the rechargeable battery.
Maintenance
Cleaning
To maintain the appearance of your watch:
- Wipe the casing and mineral glass with a soft, dry cloth.
- For the leather strap, use a slightly damp cloth and mild soap if necessary, then dry thoroughly. Avoid excessive moisture.
Water Resistance (5 Bar)
The watch is water-resistant up to 5 bar (50 meters). This means it is suitable for:
- Daily use, such as hand washing or rain.
- Showering (avoid hot water and steam).
- Brief immersion in water.
It is not suitable for swimming, diving, or prolonged water activities. Do not operate the buttons while the watch is wet.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running or displaying incorrect time. | Insufficient light exposure; poor radio signal reception. | Place the watch in direct light for several hours to charge. Ensure it is in an open area, away from electronic interference, for better signal reception. |
| Digital display is blank or dim. | Low power reserve. | Expose the watch to strong light for an extended period to fully charge the solar cell. |
| Time does not adjust automatically for daylight saving. | No radio signal received or incorrect time zone setting (if applicable). | Ensure the watch is in a location with good signal reception. Allow the watch to attempt synchronization overnight. |
