Prevent exposing your watch to shock or impact. Although all of our watches are tested for impact resistance, you should still avoid violent shocks to your watch. Apart from damaging its appearance, this can cause premature wear in materials and components, which may affect the performance of the watch.

You should also prevent exposing your watch to magnetic fields. Avoid leaving your watch close to equipment that can produce strong magnetic fields such as speakers, refrigerators, mobile phones, or magnets as these may affect the performance of your watch. A magnetized movement will cause your watch to run erratically fast or slow.

Proper care ensures that your tritium watch remains in excellent condition and continues to perform flawlessly. Start by regularly cleaning the watch with a soft, lint-free cloth to remove dust, moisture, and grime. Avoid using harsh chemicals or abrasive materials that could damage the watch's surface or tritium tubes.

Tritium watches are designed to be highly durable, but it's important to protect the watch from extreme temperatures and chemical exposure. High temperatures or contact with strong chemicals can affect the tritium's luminescence and overall functionality. Additionally, ensure that the watch's case and crown are securely sealed before exposing it to water, especially if it's a dive watch.

Avoid exposing your watch to strong magnetic fields, as they can interfere with the movement's accuracy. Regular maintenance is key; service the movement as recommended by the manufacturer to ensure it operates correctly and remains accurate.

When not in use, store your watch in a cool, dry place to prevent moisture buildup and potential corrosion. Following these simple care steps will help preserve the functionality and appearance of your tritium watch, keeping it glowing brightly and performing at its best for years to come.

Maintaining your automatic watch ensures its longevity and precision. Regular winding is essential, even if you wear it daily, to keep the movement lubricated and functioning correctly. If you don't wear the watch for a few days, use a watch winder to keep the mechanism running smoothly.

Keep your watch clean by wiping it with a soft, lint-free cloth to remove dust and moisture. For the case and bracelet, use a slightly damp cloth and mild soap to clean, but avoid immersing the watch in water unless it’s specifically designed to be waterproof.

Avoid exposing your watch to extreme temperatures and strong magnetic fields, which can affect accuracy and cause wear to the movement. Ensure the crown is always screwed down (if applicable) to maintain water resistance and prevent dust or moisture from entering the case.

Service your watch regularly as per the manufacturer’s recommendations, typically every 3 to 5 years. This includes checking the movement, cleaning, and replacing worn parts to keep it in top condition.

When not in use, store your watch in a cool, dry place and avoid direct sunlight, which can fade the dial and degrade the materials over time. By following these care guidelines, you can ensure your automatic watch remains reliable and retains its elegance for years.
