2. Configuració
2.1 Enrotllament inicial
As an automatic self-winding watch, the Alpiner 4 is powered by the motion of your wrist. If the watch has stopped or its power reserve is low, it requires manual winding to initiate operation. To manually wind the watch, unscrew the crown (if it is a screw-down crown) and turn it clockwise approximately 20-30 times. This will build up a sufficient power reserve to start the movement.
2.2 Configuració de l'hora i la data
- Unscrew and Pull Crown: Gently unscrew the crown counter-clockwise until it releases. Pull the crown out to the first position to set the date, or to the second position to set the time.
- Set Date (First Position): In the first pulled position, turn the crown clockwise or counter-clockwise (depending on the movement) to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Set Time (Second Position): In the second pulled position, turn the crown to adjust the hour and minute hands. Ensure the AM/PM is correctly set by observing the date change.
- Push and Screw Down Crown: Once the time and date are set, push the crown back into its normal position and screw it down clockwise firmly to ensure water resistance.

3. Instruccions de funcionament
3.1 Portar el rellotge
Wear the watch regularly to maintain its power reserve. The automatic movement will wind itself with the natural motion of your arm. For optimal performance, wear the watch for at least 8-10 hours daily. If the watch is not worn for an extended period, it may stop and require manual winding as described in Section 2.1.

3.2 Using the Turning Bezel
The Alpiner 4 features a turning bezel, which can be used for various timing purposes, such as measuring elapsed time. To use the bezel, rotate it to align the desired marker with the minute hand. As time passes, the minute hand will indicate the elapsed time against the bezel's scale.
3.3 Resistència a l'aigua
This watch is water resistant to 100 meters (330 feet). This rating makes it suitable for swimming and snorkeling. However, it is no recommended for diving. Always ensure the crown is fully screwed down before exposing the watch to water. Avoid operating the crown or pushers while the watch is wet or submerged.
4. Manteniment
4.1 Neteja
To maintain the appearance of your watch, clean the case and metal bracelet (if applicable) regularly with a soft, damp cloth. For leather straps, avoid excessive moisture and harsh chemicals. Allow the strap to air dry if it gets wet.
4.2 Service and Inspection
It is recommended to have your watch inspected by an authorized Alpina service center every 3-5 years to ensure optimal performance and water resistance. Regular servicing helps maintain the precision and longevity of the automatic movement.
4.3 Anti-Magnetic and Anti-Shock Features
The Alpiner 4 is designed with anti-magnetic and anti-shock properties to protect its movement from common environmental interferences. While robust, avoid exposing the watch to strong magnetic fields or severe impacts to prevent potential damage.

5. Solució De Problemes
5.1 El rellotge no funciona
If the watch is not running, it may have run out of power reserve. Manually wind the watch as described in Section 2.1. If the watch still does not start after manual winding, or stops frequently, it may require professional inspection.
5.2 Incorrect Timekeeping
Automatic watches can exhibit slight variations in timekeeping. If your watch is consistently running too fast or too slow beyond acceptable limits (typically +/- 15-30 seconds per day), it may need regulation. Contact an authorized service center for adjustment.
5.3 Date Not Changing
Ensure the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight. If the date is stuck or not advancing, avoid forcing it and consult a professional watchmaker.
