Tools Required for Removing the Back of a Watch

Removing the back of a watch requires precision and the appropriate tools to avoid damaging the case or movement. The selection of tools depends on the type of watch back, which can be snap-off, screw-down, or secured with screws.

Common tools include:

  • Case Knife: Used primarily for snap-off backs. It has a thin, flat blade designed to slip under the case back and gently pry it open.
  • Case Wrench: Specifically for screw-down backs, this tool grips the notches on the back and allows you to unscrew it.
  • Screwdrivers: Small precision screwdrivers are essential for watches with backs held on by screws.
  • Rubber Ball: A sticky rubber ball can sometimes unscrew screw-down backs by applying friction without scratching the case.
  • Protective Cloth or Pad: To place the watch on and prevent scratches during the process.

Using the right tool minimizes the risk of damage and ensures a smooth removal process.

Step-by-Step Process for Removing Different Types of Watch Backs

The method varies depending on the construction of the watch back:

Snap-off Back Removal

Begin by placing the watch face down on a soft cloth to avoid scratches. Locate the small indentation or lip on the edge of the back cover. Insert the edge of the case knife into this groove. Carefully twist or pry the knife to pop the back off. Avoid applying excessive force to prevent bending or damaging the case.

Screw-down Back Removal

This type has multiple small notches or grooves around the perimeter.

  • Align the adjustable case wrench pins with these notches.
  • Press down firmly to maintain contact.
  • Turn the wrench counterclockwise slowly to unscrew the back.
  • If resistance is too high, a rubber ball can be pressed firmly against the back and twisted to loosen it.

Screw-secured Back Removal

Some watches have small screws securing the back.

  • Use a precision screwdriver that fits the screws perfectly.
  • Unscrew each one carefully and keep them organized.
  • Lift the back cover gently once all screws are removed.

Tips for Handling and Protecting Watch Components

Handling delicate watch parts requires care to prevent damage or contamination.

  • Always work in a clean, dust-free environment.
  • Use finger cots or gloves to avoid transferring oils from your skin.
  • Place removed backs and screws in a designated container.
  • Avoid touching the movement or internal components directly.
  • After removal, inspect the gasket or rubber seal for damage; replace if necessary to maintain water resistance.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
