Setup
Setting the Time

- Push the crown back in to the normal position to start the timekeeping.
Setting the Day and Date
- Pull the crown out to the first click position.
- Turn the crown clockwise to adjust the date.
- Turn the crown counter-clockwise to adjust the day of the week.
- Avoid setting the day and date between 9:00 PM and 4:00 AM, as this may interfere with the automatic date change mechanism.
- Once the day and date are set, push the crown back in to the normal position.
Operating the Watch
Wearing the Watch
The watch features a stainless steel bracelet with a push-button clasp. To open the clasp, press the buttons on the sides of the clasp. To close, align the two parts of the clasp and press firmly until it clicks securely.
Water Resistance
This watch is rated for 30 meters (3 ATM) of water resistance. This means it is suitable for everyday use and can withstand splashes or brief immersion in water. It is not suitable for swimming, diving, or showering. Avoid operating the crown while the watch is wet.
Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and band with a soft, dry cloth regularly. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners or abrasive materials.
Battery Replacement
The watch is powered by one LR44 battery. When the watch stops or the hands move erratically, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance.
Troubleshooting
- Watch not running: Check if the crown is pushed in completely. If it is, the battery may need replacement.
- Incorrect time/date: Refer to the "Setting the Time" and "Setting the Day and Date" sections to re-adjust.
- Condensation inside the watch: This may indicate a loss of water resistance. Contact a service center immediately.
