There are different types of watch caseback which means they need different treatments to be removed. Commonly there are two types of watch caseback includes snap-off and screw-down caseback.

How to Remove Watch Caseback

Removing a watch case back takes several steps that need a keen eye and careful treatment. So, make sure you follow every step appropriately as mentioned in the tutorial below.

Get the Tools to Remove Watch Caseback

Before attempting to remove the watch caseback, it’s crucial to have the right tools at hand. The following tools will help you accomplish the task efficiently:

  • Caseback removal tool (case knife or caseback wrench)
  • Non-slip work surface
  • A soft cloth or watchmaker’s pad
  • Rubber gloves (optional)
  • Plastic container for storing screws or other small parts

Prepare Your Workshop

Choose a clean, well-lit workspace with ample room to maneuver. Lay down a non-slip work surface, such as a soft cloth or a watchmaker’s pad, to prevent your watch from sliding or getting scratched. 

Additionally, consider wearing rubber gloves to ensure a firm grip and protect the watch from fingerprints or oils from your hands.

Determine the Type of Caseback

As mentioned above, there are two common types of watch casebacks: screw-down and snap-off. Screw-down casebacks feature small grooves around the circumference and require a specific tool for removal. 

Snap-off casebacks, on the other hand, have no visible screws and can be popped off using a case knife. Identify the type of caseback your watch has before proceeding.

Removing a Screw-Down Caseback

For a screw-down caseback, follow these steps:

  • Place your watch face down on the non-slip work surface.
  • Select the appropriate size of the caseback wrench that matches the grooves on the caseback.
  • Fit the wrench into the grooves and apply gentle, steady pressure counterclockwise to unscrew the caseback.
  • Once the caseback becomes loose, carefully turn it the rest of the way with your fingers.
  • Set the caseback aside in a safe place.
