2. Setup
2.1 Setting the Time
- Pull the crown (the small knob on the side of the watch case) out to the first position.
- Turn the crown clockwise or counter-clockwise to adjust the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its original position to start the watch movement.
2.2 Adjusting the Stainless Steel Band
The stainless steel band may require adjustment to fit your wrist comfortably. This typically involves adding or removing links. It is recommended to have this procedure performed by a professional watchmaker or jeweler to prevent damage to the band or watch.

If a band adjustment tool is provided, carefully follow its specific instructions for removing or adding links. Ensure all pins are securely reinserted after adjustment.
3. Operating the Watch
Your D1 Milano UTBJ12 watch is an analog timepiece powered by a Quartz movement. Once the time is set and the crown is pushed in, the watch will continuously display the current time. No further regular operation is required beyond setting the time as needed (e.g., for daylight saving changes).
3.1 Water Resistance
This watch has a water resistance rating of 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown while the watch is wet or submerged to prevent water ingress.
4. Maintenance
4.1 Cleaning
- Wipe the watch case and sapphire crystal with a soft, dry, lint-free cloth to remove dust and fingerprints.
- For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive materials.
4.2 Battery Replacement
The watch is powered by a standard watch battery. When the watch stops running, it indicates the battery needs replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure the watch's water resistance is maintained and to prevent damage to the internal components.
4.3 Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box provides excellent protection.
