      FAQs

      How do I choose the right size and fit for a watch?

      In general, we recommend the following case size according to the wrist size:

      Small Wrist (6 inch) - 40mm or below

      Medium Wrist (7 - 7.5 inch) - 40 - 42mm

      Large Wrist (8 inch+) - 44mm or above

      For more detailed guidance, please refer to the ‘See the Fit’ link at the top of the product page.

      How to maintain the movement of my watch to the best possible condition?

      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.

      How to care your tritium watch?

      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.

      How to care your automatic watch?

      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.

      Colour accuracy

      Despite every effort to provide accurate images of each product’s colour and design, actual colours may vary slightly. This is due to computer monitors or smartphones displaying colours differently and everyone can see these colours differently. We try extremely hard to ensure our photos are as life-like as possible.

      What is the delivery time after I place an order?

      All orders are shipped within 3 business days, unless indicated otherwise.

      We use FedEx delivery service and it takes an average of 5-10 business days (not including weekends and public holidays) to be received once dispatched from our warehouse.

      Does Aquatico offer any warranty or guarantee for the watches?

      Yes, all our watches are covered by a 2 years international warranty, starting from the date of purchase.

      What is Aquatico return policy?

      If you are unhappy with your purchase, you can return it to us within 14 days of delivery. For more details, please visit our refund policy.
