Setup
Initial Charging:
Upon receiving your watch, expose the dial to a strong light source (natural sunlight is ideal) for several hours to ensure a full charge. The watch has a power reserve of up to 6 months when fully charged.
Time Synchronization (Radio Control):
The watch automatically attempts to receive the DCF 77 radio signal daily to synchronize the time. For optimal reception, place the watch near a window, away from electronic devices that may cause interference. The signal is broadcast from Mainflingen, Germany, and covers a range of approximately 1,000 km.

If manual time setting is required due to being outside the reception range or signal interference, refer to the "Operating" section for manual adjustment procedures.
Bracelet Adjustment:
The stainless steel bracelet can be adjusted to fit your wrist. This typically involves removing or adding links. It is recommended to have this procedure performed by a qualified jeweler or watch technician to prevent damage.

Operating
Basic Time Display:
The watch displays time using both analog hands and digital displays. The analog hands show the primary time, while the digital displays provide additional information such as date, day, and world time.
Using the Chronograph (Stopwatch):
- Press Button A (typically top right) to start the stopwatch.
- Press Button A again to pause.
- Press Button B (typically bottom right) to reset the stopwatch to zero.
World Time Function:
To access and set the World Timer for 38 cities:
- Refer to the specific button combination in your full manual (not provided here) to enter World Time mode.
- Use the designated buttons (e.g., Button B) to cycle through the available cities.
- The digital display will show the time for the selected city.
Illumination:
Press the illumination button (refer to watch diagram for exact location, typically a side button) to activate the backlight for the digital displays and/or luminous hands/digits.
Automatic Summer/Winter Time Change:
The radio-controlled function automatically adjusts for daylight saving time (summer/winter time) changes in regions where the DCF 77 signal is received.
Maintenance
Cleaning:
Wipe the watch regularly with a soft, dry cloth to remove dust and fingerprints. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.
Water Resistance:
The watch is water resistant up to 10 bar (100 meters). This means it is suitable for showering, swimming, and snorkeling. Do not operate the crown or buttons while the watch is wet or submerged to prevent water ingress.
Solar Charging:
To maintain optimal power reserve, ensure the watch is regularly exposed to light. Avoid prolonged storage in dark places. The watch features a low energy display and a sleep function to conserve power when not in use or in darkness.
Storage:
When storing the watch for extended periods, place it in an area where it can receive some light to prevent the power reserve from depleting completely.
Troubleshooting
