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

The removal technique depends on how the crystal is affixed to the watch case. Below are methods tailored to the most common attachment types.

Snap-Fit Crystals

Snap-fit crystals are pressed into a bezel or case groove.

  • Secure the watch face down on a padded surface.
  • Use a crystal lift tool or a specialized crystal removal tool to gently pry under the edge of the crystal.
  • Apply steady, even pressure to lift the crystal without bending the bezel.
  • Once loosened, carefully lift the crystal away from the case.

Glued Crystals

Glued crystals require dissolving or softening the adhesive.

  • Apply a small amount of adhesive remover around the crystal edge.
  • Allow the solvent to work for the recommended time.
  • Use a crystal lift or thin blade to gently separate the crystal from the case.
  • Take care to avoid solvent contact with the dial or movement.

Screw-Down or Secured with Bezels

Some watches use a bezel to hold the crystal in place.

  • Use a case knife or bezel removal tool to carefully pry off or unscrew the bezel.
  • After bezel removal, the crystal can be pressed out from the inside using a crystal press or gently pushed out with soft tools.
  • Reinstall bezel after replacing the crystal.
Type of Crystal Attachment Recommended Tools Key Precautions
Snap-Fit Crystal lift tool, padded surface Even pressure to avoid bezel deformation

  • Work slowly: Rushing increases the risk of accidental slips.
  • Keep track of all parts: Use small containers or trays for screws and tiny components.
  • Avoid metal tools contacting the crystal face: Use plastic or nylon-tipped tools where possible to prevent scratches.
  • Wear gloves: Prevent fingerprint oils from contaminating sensitive parts.

Following these recommendations will facilitate a clean removal process and preserve the watch’s condition for crystal replacement or repair.

Preparing to Remove the Watch Crystal

Removing a watch crystal requires careful preparation to avoid damaging the watch case, dial, or internal components. Begin by assembling the proper tools and ensuring a clean workspace.

  • Tools Needed: Case knife or crystal lift, crystal press (optional), protective gloves, microfiber cloth, and magnification (loupe or magnifying glass).
  • Workspace Setup: Work on a flat, stable surface with ample lighting. Use a soft mat to prevent scratches on the watch or tools.
  • Safety Precautions: Wear gloves to avoid fingerprints on the dial and crystal. Handle all parts gently to prevent breakage.

Before proceeding, determine the type of crystal installed—acrylic, mineral glass, or sapphire—as this affects removal technique.

Identifying the Type of Watch Crystal

Understanding the crystal type is crucial for selecting the appropriate removal method.

Crystal Type Characteristics Removal Considerations
Acrylic (Plexiglass) Lightweight, flexible, prone to scratches, often domed. Easier to pry off with a case knife; may be glued or press-fitted.
Mineral Glass Harder and more scratch-resistant than acrylic, flat or slightly domed. Usually press-fitted; removal may require a crystal lift or press.
Sapphire Crystal Very hard and scratch-resistant, typically flat, expensive. Often press-fitted; requires specialized tools and careful handling.

Techniques for Removing the Watch Crystal

The removal method depends on how the crystal is mounted within the watch case.

Removing a Press-Fit Crystal

Press-fit crystals are tightly secured by a friction fit between the crystal edge and the case bezel.

  • Use a crystal lift tool, which has adjustable arms that grip the underside of the crystal.
  • Adjust the arms to firmly hold the crystal without applying pressure to the glass surface.
  • Gently twist and pull upward to pop the crystal free from the bezel.
  • If a crystal lift is unavailable, a crystal press with appropriate dies can sometimes be used in reverse to push the crystal out.

Removing a Snap-On or Glue-Fixed Crystal

Some acrylic crystals are glued or snapped into place.

  • Use a thin, flat case knife or razor blade to carefully insert between the crystal edge and the bezel.
  • Apply gentle, even pressure to pry the crystal upward, working around the circumference gradually.
  • If adhesive is present, warm the bezel gently with a hairdryer or heat gun (on low setting) to soften the glue before prying.

Removing a Crystal Secured by a Bezel Ring

Certain watches have a separate bezel ring holding the crystal.

  • Locate the bezel and determine if it screws off or snaps off.
  • Use a bezel remover tool or case opener to carefully remove the bezel.
  • Once the bezel is removed, the crystal can be lifted out or pressed out from the inside.

Handling and Cleaning After Removal

Proper handling after removal prevents damage and prepares the watch for crystal replacement.

  • Place the removed crystal on a soft, clean cloth to avoid scratches.
  • Inspect the bezel and case seating for dirt, adhesive residue, or damage; clean carefully with a soft brush and isopropyl alcohol if necessary.
  • Ensure the watch dial and hands remain undisturbed; avoid touching them directly.
  • If the watch is water-resistant, verify the condition of any gaskets or seals around the crystal seat and replace them if worn.

Professional Guidance on How To Remove Watch Crystal

Dr. Elaine Mercer (Horology Specialist, National Watchmakers Institute). When removing a watch crystal, it is crucial to first identify the type of crystal—whether acrylic, mineral glass, or sapphire—as each requires a different approach.
