How can I open my watch?

Published in Watch Repair 2 mins read

Opening a watch depends on the type of case back it has. Here's a breakdown of common methods:

1. Identifying Your Watch Case Back:

Before you begin, identify what type of case back your watch has. Common types include:

  • Snap-On/Pop-Off Case Back: These are held in place by pressure and usually have a small lip or indentation.
  • Screw-Down Case Back: These have grooves or notches around the perimeter and screw into the watch case.
  • Multiple-Screw Case Back: These are held in place by several small screws.

2. Opening a Snap-On/Pop-Off Case Back:

  • Tools Needed: Watch case opener tool (a thin, wedge-shaped tool) or a very fine, sturdy knife.
  • Procedure:
    1. Locate the small lip or indentation on the case back.
    2. Carefully insert the tip of the case opener into the indentation.
    3. Gently twist the tool to pry the case back open. Avoid forcing it. Work your way around the case back gradually.
    4. Once you have a gap, you may be able to insert a plastic opening tool to widen the gap and fully remove the back.
    5. Caution: Be careful not to scratch the case or damage the movement.

3. Opening a Screw-Down Case Back:

  • Tools Needed: Watch case wrench (adjustable tool with pins) or a case back remover tool that fits the grooves/notches.
  • Procedure:
    1. Adjust the wrench or tool to fit the notches on the case back.
    2. Ensure the tool is securely engaged with the notches to prevent slipping.
    3. Apply gentle pressure and turn the case back counter-clockwise to unscrew it.
    4. Once loose, you can usually unscrew it the rest of the way by hand.

4. Opening a Multiple-Screw Case Back:

  • Tools Needed: Small screwdrivers of appropriate size.
  • Procedure:
    1. Carefully unscrew each screw.
    2. Keep track of the screws to avoid losing them.
    3. Once all screws are removed, the case back should lift off.

Important Considerations:

  • Cleanliness: Work in a clean and well-lit area to avoid contamination or losing small parts.
  • Patience: Don't force anything. If it's not opening easily, re-evaluate your technique.
  • Professional Help: If you're uncomfortable or unsure, it's always best to take your watch to a professional watch repairer. You risk damaging the watch movement if done incorrectly.
