4. Cura i Manteniment
4.1 Neteja
Netegeu regularment la caixa i la corretja del rellotge amb un drap suau i sec per eliminar la brutícia i la humitat. Per a la corretja d'acer inoxidable, una lleugera damp es pot fer servir un drap, seguit d'un drap sec. Eviteu utilitzar netejadors químics o materials abrasius.
4.2 Substitució de la bateria
The watch is powered by a Lithium-Ion battery. When the watch stops or the hands move erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure water resistance is maintained.
