1. Introduzione
The SEIKO SNK809 is an automatic mechanical watch designed for reliable timekeeping and durability. This manual provides essential information for setting up, operating, and maintaining your watch.

- Ruota la corona to adjust the hour and minute hands to the correct time.
- Riportare la corona nella posizione del primo scatto. This allows for date and day adjustment.
- Ruota la corona to adjust the date and day. Note that the day can be set in English or another language.

3. Funzionamento
3.1 Movimento automatico
Your SEIKO SNK809 watch is powered by an automatic mechanical movement, meaning it does not require batteries. It is powered by the natural motion of your arm. Consistent wear for 8 hours or more per day is recommended to maintain optimal accuracy. If the watch is not worn regularly, its mainspring may unwind, affecting timekeeping accuracy. The mainspring can also be manually wound by turning the crown in the normal position.
3.2 Resistenza all'acqua
This watch is water resistant to 30 meters (100 feet). This rating means it is suitable for splashes or brief immersion in water. It is non recommended for swimming, diving, or prolonged water activities.

4. Manutenzione
4.1 Pulizia
- Pulisci la cassa e il cristallo dell'orologio con un panno morbido e asciutto per rimuovere polvere e macchie.
- For the canvas strap, a slightly damp cloth can be used for cleaning. Ensure the strap dries completely before wearing.
4.2 Conservazione
- Quando non lo si utilizza, conservare l'orologio in un luogo asciutto, lontano dalla luce solare diretta e da temperature estreme.
- An automatic watch winder can be used to keep the watch running and accurate if not worn for extended periods.
4.3 Evitamento
- Evitare di esporre l'orologio a forti campi magnetici, poiché ciò potrebbe compromettere la precisione della misurazione del tempo.
- Protect the watch from harsh chemicals, solvents, and sudden impacts.
5. Risoluzione Dei Problemi
5.1 Cronometraggio impreciso
If the watch loses or gains significant time, ensure it is being worn consistently for at least 8 hours a day. Insufficient winding is a common cause of inaccuracy in automatic watches. If the issue persists after ensuring adequate wear, professional servicing may be required.
5.2 Watch Stops
If the watch stops, it likely needs to be wound. Gently swing it horizontally for 30 seconds or manually wind the crown to restart it. If it still does not start, consult a service professional.
