Carefully remove your Omega Seamaster watch from its packaging. Inspect the watch for any visible damage. Ensure all accompanying documents, including the warranty card and instruction manual, are present.

2.2 Carica manuale
Your Omega Seamaster 2222.80 is an automatic mechanical watch. If the watch has stopped, it requires manual winding to initiate movement. To manually wind the watch:
- Unscrew the crown counter-clockwise until it springs out to position 1.
- Ruotare la corona in senso orario circa 20-30 volte. Questo fornirà una riserva di carica sufficiente per avviare il movimento.
- The watch will then continue to wind itself through the motion of your wrist while worn. A full power reserve is approximately 48 hours.
2.3 Impostazione dell'ora e della data
Per impostare l'ora e la data sul tuo orologio:
- Impostazione della data: Pull the crown out to position 2. Turn the crown either clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Impostazione dell'ora: Pull the crown out to position 3. The seconds hand will stop. Turn the crown to set the hour and minute hands. To ensure precise time setting, synchronize with a reliable time source.
- Once the time and date are set, push the crown back into position 1 and screw it clockwise firmly against the case to ensure water resistance.
3. Funzionamento
3.1 Lunetta girevole unidirezionale
The Omega Seamaster 2222.80 features a unidirectional rotating bezel, which is a crucial safety feature for divers. It rotates only counter-clockwise to prevent accidental increases in dive time. To use the bezel:
- Align the triangle marker on the bezel with the minute hand at the start of your dive or timed event.
- La lancetta dei minuti indicherà quindi il tempo trascorso sulla scala della lunetta.
- The unidirectional rotation ensures that if the bezel is accidentally moved, it will only indicate a shorter elapsed time, thus providing a safety margin for divers.
3.2 Resistenza all'acqua
Your Omega Seamaster 2222.80 is water resistant to 300 meters (1000 feet). This makes it suitable for professional diving, including scuba diving to a depth of 30 meters for up to 2 hours. To maintain water resistance:
- Always ensure the crown is fully screwed down against the case before exposing the watch to water.
- Non azionare la corona o i pulsanti (se presenti) mentre l'orologio è immerso o bagnato.
- Dopo l'esposizione all'acqua salata, sciacquare abbondantemente l'orologio con acqua dolce e asciugarlo con un panno morbido.
Importante: Water resistance is not a permanent condition and may be affected by aging gaskets or accidental impacts. Regular checks are recommended.
4. Cura e manutenzione
4.1 Pulizia
To clean your Omega Seamaster watch:
- Utilizzare un morbido, damp cloth to wipe the case and bracelet.
- For more thorough cleaning, especially after swimming in chlorinated or saltwater, use a mild soap solution and a soft brush, ensuring the crown is fully screwed down. Rinse thoroughly with fresh water afterwards.
- Dry the watch completely with a soft, lint-free cloth.
4.2 Intervalli di manutenzione
Like any precision instrument, your Omega automatic watch requires periodic servicing to ensure optimal performance and longevity. It is recommended to have your watch serviced by an authorized Omega service center every 5-7 years. This service typically includes:
- Complete disassembly, cleaning, and lubrication of the movement.
- Sostituzione dei componenti usurati.
- Restoration of water resistance (replacement of gaskets).
- Case and bracelet cleaning and refinishing.
4.3 Precauzioni generali
- Evitare di esporre l'orologio a temperature estreme (superiori a 60°C / 140°F o inferiori a 0°C / 32°F) o a sbalzi di temperatura improvvisi.
- Keep the watch away from strong magnetic fields, which can affect the accuracy of the mechanical movement.
- Proteggi il tuo orologio da urti e colpi.

| Problema | Possibile causa | Soluzione |
|---|---|---|
| L'orologio si è fermato o funziona in modo impreciso. | Riserva di carica insufficiente. | Manually wind the watch by turning the crown clockwise 20-30 times (after unscrewing it to position 1). Wear the watch regularly to keep it wound. |
| La data non cambia a mezzanotte. | L'ora è impostata su AM anziché PM, o viceversa. | Avanti di 12 ore. Assicurati che la data cambi intorno a mezzanotte, non a mezzogiorno. |
