Manutenzione
Una cura adeguata garantirà la longevità e le prestazioni del tuo orologio G-Shock.
- Resistenza all'acqua (200M): Your watch is water-resistant to 200 meters. This means it is suitable for showering, swimming, and shallow diving. Non azionare i pulsanti mentre l'orologio è immerso nell'acqua. Evitare di esporre l'orologio ad acqua calda o vapore, poiché ciò potrebbe compromettere le guarnizioni.
- Pulizia: Pulisci la cassa e il cinturino dell'orologio con un panno morbido e asciutto. Per lo sporco ostinato, usa un panno morbido.ampened with water and a mild neutral detergent, then wipe dry. Avoid harsh chemicals or solvents.
- Batteria: The watch uses a Lithium Metal battery (CR1220). Battery life is approximately 2 years. When the display becomes dim or functions become unstable, it is time to replace the battery. We recommend having battery replacement performed by an authorized Casio service center to ensure water resistance is maintained.
- Temperature estreme: Avoid exposing your watch to extreme temperatures, both hot and cold, for extended periods.
