Tips for Maintaining Your Watch

To keep your Seiko or Casio watch in excellent condition, consider these maintenance tips:

• Avoid Extreme Temperatures: Exposure to extreme heat or cold can damage the watch's internal components. Store your watch in a temperature-controlled environment.

Even with proper maintenance, issues can arise. Here are some common problems and solutions:

• Watch Not Working: If your watch isn’t functioning, it may be due to a dead battery. Replace the battery as outlined above.
• Moisture Inside the Watch: If you notice condensation on the watch face, it may indicate a seal failure. Have it checked by a professional immediately.
