1. Introduktion
The Citizen Eco-Drive Corso Classic Watch (Model: BU2070-12L) is a timepiece designed for reliability and functionality. This watch features Citizen's Eco-Drive technology, which powers the watch using any light source, eliminating the need for regular battery replacement. It includes a stainless steel case, a brown leather strap, a blue dial, and displays for day, date, and 12/24-hour time.

2. Opsætning
2.1 Indledende opladning
Upon receiving your watch, ensure it is fully charged by exposing the dial to a bright light source (natural or artificial) for several hours. The Eco-Drive movement stores energy in a power cell, allowing the watch to operate for extended periods in darkness once fully charged.

- Rotate the crown to set the day and date.

3. Betjening
3.1 Tidtagning
The watch displays time using hour, minute, and second hands. It also features a 12/24-hour sub-dial for military time or a second time zone reference.
3.2 Day and Date Display
Separate sub-dials on the watch face indicate the current day of the week and the date.
3.3 Gangreserve
The Eco-Drive movement ensures continuous operation as long as the watch is exposed to light. Once fully charged, the watch can operate for several months in complete darkness. If the watch's power reserve becomes low, the second hand may begin moving in two-second intervals as a warning. Expose the watch to light to resume normal operation.

4. Vedligeholdelse
4.1 Rengøring
Regularly wipe the watch case and sapphire crystal with a soft, dry cloth to remove dust and smudges. For the brown leather strap, use a slightly damp cloth and mild soap if necessary, then dry thoroughly. Avoid harsh chemicals or abrasive materials that could damage the watch or strap.
4.2 Vandtæthed
This watch is water resistant to 100 meter (333 fod). It is suitable for swimming and snorkeling but not for scuba diving. Always ensure the crown is pushed in completely before any water exposure. Do not operate the crown or pushers while the watch is wet or submerged.
4.3 Light Exposure and Storage
To maintain optimal performance and ensure continuous operation, expose the watch to light regularly. When not in use, store the watch in a location where it can receive ambient light, or in a well-lit area, to prevent the power cell from depleting.

5. Fejlfinding
- Uret kører ikke: If the watch stops or the second hand moves erratically (e.g., in two-second intervals), it indicates insufficient charge. Expose the watch to bright light for several hours to recharge the power cell.
- Forkert tidspunkt/dato: Follow the "Setting the Time and Date" instructions in Section 2.2 to correct any discrepancies.
- Kondensation under krystal: If condensation appears under the crystal, contact Citizen customer service immediately. This may indicate a breach in water resistance that requires professional inspection and repair.
