• Place the watch where the dial is exposed to direct light (natural or artificial).
• Avoid placing the watch in direct sunlight for extended periods in hot environments to prevent overheating.
• A full charge can take several hours depending on the light intensity.

• Evite calor extremo: Do not place the watch directly under intense sunlight for prolonged periods, especially in hot environments, as this can damage the movement.
• Artificial Light: Fluorescente lamps and other artificial light sources can also charge the watch, though it may take longer than natural sunlight.
