5. Maintenance
5.1 Water Resistance
Your watch is water-resistant up to 100 meters (10 ATM). This means it is suitable for everyday use, including splashes, rain, and recreational swimming. However, it is not recommended for diving or hot baths/showers, as extreme temperature changes and steam can compromise the seals. Always ensure the crown is fully pushed in before exposing the watch to water.
5.2 Cleaning
To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For stainless steel parts, a slightly damp cloth can be used, followed by a dry one. Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish or seals. A cleaning cloth is included with your purchase.
5.3 Luminous Features
The hands and markers of your watch feature luminous material, allowing for readability in low-light conditions. Exposure to light will charge the luminous elements, which will then glow in the dark for a period.
