Step-by-Step Repair Guide

Alright, let’s get our hands dirty, shall we? I will guide you through some of the most common repairs you might encounter with your Casio AMW-701. Remember to work in a well-lit, clean area. Patience is key!

1. Battery Replacement

This is often the first step, and it’s the easiest. Even if your watch has other issues, a dead battery can be the root cause. Here’s what you do:

  1. Open the Case: Use your case opener to carefully remove the back of the watch. Note the type of case back (screw-on, snap-on).
  2. Locate the Battery: Look for the battery holder. It's usually held in place by a small metal clip.
  3. Remove the Old Battery: Use your tweezers or a non-metallic tool to gently remove the old battery. Be careful not to short-circuit any components!
  4. Insert the New Battery: Make sure the positive (+) and negative (-) terminals are correctly aligned. The correct orientation should be marked inside the watch. It is very important that you put the battery in correctly.
  5. Replace the Case Back: Ensure the gasket is in good shape. Carefully close the back, ensuring it seals properly. If it is a screw-on case, screw it back. If it’s a snap-on case, snap it shut.
  6. Test the Watch: Check if the watch functions correctly. If it doesn't work, ensure the battery is seated properly or may need to be reset.

2. Digital Display Issues

If the digital display is malfunctioning, you’ll need to do some more in-depth troubleshooting. Here's how to go about it:

  1. Check the Battery: As always, start with a new battery. Low power can cause display issues.
  2. Inspect the LCD: Look for signs of damage or leakage. If you see discoloration, it may need to be replaced. Liquid damage is one of the most common causes.
  3. Clean the Contacts: Use isopropyl alcohol and a clean cloth to clean the contacts between the LCD and the circuit board.
  4. Check the Circuit Board: Look for any signs of corrosion or damage. If you see damaged components, you may need to replace them. This might be a bit too advanced if you are a beginner. It is always a good idea to bring it to a professional. If you decide to do it yourself, you will need to get a new circuit board and replace the old one.
  5. Reassemble and Test: If cleaning doesn't work, you may need a new LCD or a professional repair.

3. Button Repair

Buttons that stick or don’t respond can be annoying. Here's how to fix them:

  1. Disassemble the Watch: Remove the back and carefully remove the movement from the case. The movement is the entire mechanism inside the watch.
  2. Locate the Buttons: You will see the buttons, and they attach to the main body.
  3. Clean the Buttons: Use isopropyl alcohol to clean the button contacts and the holes where the buttons go. Dirt or debris is usually the culprit.
  4. Inspect the Springs: Ensure the springs are not damaged or bent. If bent, carefully adjust them to their original shape.
