Setup
Setting the Time and Date
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) to the second click position.
- Set the time: Turn the crown to adjust the hour and minute hands to the correct time. Ensure you differentiate between AM and PM for the date change.
- Set the date: Push the crown back to the first click position. Turn the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the date change mechanism.
- Push in the crown: Once the time and date are set, push the crown back into its normal position to start the watch.
Adjusting the Watch Band
The gold stainless steel bracelet features removable links for a customized fit. It is recommended to have a professional jeweler adjust the band to ensure proper fit and to avoid damage to the watch or band.

Maintenance
Cleaning
To maintain the appearance of your watch, regularly wipe the case and bracelet with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
Water Resistance
The watch is water-resistant up to 100 meters (330 feet) or 10 ATM. This means it is suitable for recreational swimming, snorkeling, and shallow diving. However, it is crucial to ensure the crown is fully pushed in before any water exposure. Do not operate the crown or pushers while the watch is wet or submerged.
Battery Replacement
The watch is powered by a quartz movement and requires a battery. When the battery needs replacement, it is recommended to take your watch to an authorized Diesel service center or a reputable jeweler. This ensures the correct battery type is used and the water resistance seal is properly maintained.

Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Time or date not setting: Ensure the crown is pulled out to the correct position (first click for date, second click for time). Avoid setting the date during the automatic date change period (9 PM - 3 AM).
- Chronograph hands not resetting to zero: This may require a chronograph reset procedure. Consult an authorized service center if the issue persists after following the operating instructions.
- Water inside the watch: If you notice condensation or water inside the watch, immediately take it to an authorized service center. This indicates a compromised water resistance seal.
