Impostare
Avvolgimento iniziale
Your Zenith automatic watch is powered by the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it requires an initial manual winding to build up its power reserve.
- Assicurarsi che la corona sia completamente inserita (posizione 0).
- Turn the crown clockwise approximately 30-40 times. This will provide sufficient power for the watch to start running and for the automatic winding mechanism to take over.
Impostazione dell'ora
To set the correct time on your watch:
- Estrarre delicatamente la corona fino alla posizione 1.
- Turn the crown either clockwise or counter-clockwise to move the hands and set the desired time.
- Once the time is set, push the crown back into position 0 to engage the movement and ensure water resistance.

Utilizzo dell'orologio
Movimento automatico
Your Zenith watch is equipped with an automatic mechanical movement. This means it is powered by the natural motion of your wrist. As you wear the watch, an oscillating weight inside the movement rotates, winding the mainspring and storing energy. If worn regularly (approximately 8-12 hours a day), the watch will maintain its power reserve without manual winding.
Resistenza all'acqua
The Zenith Pilot Montre D'aeronef Type 20 watch has a water resistance rating of 100 meters (330 feet). This rating indicates that the watch is suitable for swimming and snorkeling. It is not recommended for diving. Always ensure the crown is fully pushed in before exposing the watch to water. Avoid operating the crown while the watch is wet or submerged, as this can compromise its water resistance.

Manutenzione
Pulizia
Per mantenere l'aspetto del tuo orologio:
- Caso: Wipe the bronze case with a soft, dry cloth. Bronze naturally develops a patina over time, which is part of its character. If you wish to restore its original luster, consult a professional watchmaker or use a specialized bronze cleaning cloth.
- Cinghia: The nubuck leather strap should not be submerged in water. Clean it with a soft, slightly damp cloth and allow it to air dry completely. Avoid harsh chemicals or excessive moisture, which can damage the leather.
Servizio periodico
Like any precision mechanical instrument, your Zenith watch requires periodic professional servicing to ensure its accuracy and longevity. It is recommended to have your watch serviced by an authorized Zenith service center every 3-5 years. Regular servicing includes cleaning, lubrication, and adjustment of the movement, as well as checking the water resistance seals.
Magazzinaggio
When not wearing your watch, store it in its original box or a watch winder to protect it from dust, moisture, and accidental damage. If storing for an extended period, ensure the watch is fully wound before storage.

Risoluzione dei problemi
- L'orologio si è fermato: If the watch has stopped, it likely needs to be wound. Manually wind the watch by turning the crown clockwise 30-40 times. If it still does not start, or stops shortly after, it may require professional servicing.
- Cronometraggio impreciso: Minor variations in timekeeping are normal for mechanical watches. However, if your watch is consistently gaining or losing significant time, it may need adjustment by an authorized service center.
- Condensazione sotto il cristallo: If you notice condensation or moisture inside the watch, this indicates a breach in the water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
