Pengecasan Awal
Before first use, or if the watch has stopped, ensure it is fully charged. Expose the watch dial to bright light (e.g., sunlight or fluorescent lamp) for several hours. The charging time varies depending on the light source intensity. A fully charged Eco-Drive watch can run for an extended period in the dark.
