Warranty and Service

Warranty

  • All AJH Watches come with a 12-month (1 year) warranty from the date of purchase.

  • The warranty covers manufacturing and material defects.

  • The warranty does not cover:

    • normal wear and tear (scratches on glass, case, or bracelet)

    • water damage caused by misuse or failure to follow the instructions

    • damage caused by impact, dropping, or improper handling

    • servicing or repairs not carried out by an AJH authorized service partner.

If you encounter any issues, please contact our customer service by email. We will provide instructions for returning the watch and inspect the situation.

Service

  • A watch is a precise mechanical instrument that requires regular maintenance.

  • Quartz movements (VK63): battery life is typically 2–3 years. Replace the battery at a professional watchmaker.

  • Automatic movements (NH35, NH34, SW200, etc.): we recommend a full service every 4–6 years (cleaning, lubrication, and gasket check).

  • Water-resistance and gaskets should be checked every 2–3 years, especially if the watch is used in water.

  • The watch can be gently cleaned with lukewarm water and a soft cloth. Do not use chemicals.

  • Seiko movements (VK63, NH34, NH35) are known worldwide, which means that servicing and battery replacements can be done by most professional watchmakers.

Special instructions for AJH VK63 chronographs

  • The watch is water-resistant, but never operate the chronograph pushers under water. When swimming or showering, make sure the pushers and crown are fully closed.

  • Do not change the date between 9 PM and 3 AM. During this time, the date-change mechanism is engaged and forcing it may permanently damage the movement.

Special instructions for AJH NH34 / NH35 automatics

  • Always ensure the crown is fully secured before exposing the watch to water.

  • Do not change the date between 9 PM and 3 AM – the same rule applies to these movements.

Usage tips

  • Avoid strong impacts and magnetic fields (e.g. speakers, induction cooktops).

  • Always close the crown carefully before contact with water.

  • If your watch has a screw-down crown, do not overtighten it.

  • Store the watch in a dry, protected place when not in use.
