Entretien
Remplacement de la batterie
The watch uses one Lithium Metal battery (CR2025). When the battery needs replacement, it is recommended to have it done by a qualified watch technician to ensure the water resistance seal is properly re-inserted. Improper battery replacement can compromise the watch's water resistance.
Directives de résistance à l'eau
Your watch is water-resistant to 100 meters (330 feet). This makes it suitable for snorkeling, swimming, and showering. However, it is not recommended for scuba diving. Avoid pressing buttons underwater to prevent water ingress.
