How to replace a watch crystal – Step by Step Guide 

We will be utilizing the following tools during this guide…

  • Screwdrivers
  • Headset magnifier
  • Blower à main
  • Millimetre Indicator
  • Tweezers
  • A back press of Crystal/Case
  • Mallet Made of Rubber or Rawhide


Step 1

Check Warranty of Watch

Verify the validity of your warranty. Certain watch manufacturers and retailers provide free crystal replacement for a limited or indefinite time.

For example, Tourneau, one of the top watch retailers in the world, provides an extended warranty protection package.

Step 2

Replacement Crystal of the Right Size

To begin, wipe off your bench or tabletop. It’s recommended to use a watch pad, but a thick towel will suffice if you don’t have one. Suppose the watchband is leather and can be split apart.

Remove a pin or screw from the band if it is metal or a “closed-loop” band to allow you to open it up and have access to the rear of the watch.

We have a closed-loop band in this example, and I remove a pin from the buckle to provide unrestricted access to the inside of the watch.

Step 3

Remove the old crystal

Make sure the jaws of the crystal lift are broader than the watch crystal. Place the crystal lift on top of the crystal and tighten the jars until they grasp the crystal’s side.

Try to raise the crystal by holding the watch casing. If the crystal lift is challenging to grow, tighten it a little more.

Step 4

Make sure the inside of the bezel is clean

This is the ideal opportunity to clean the interior of the bezel so that the new crystal fits perfectly.

Dust and grime accumulate between the crystal and the bezel over time. To clean it, use a gentle brush and a hand pump. Make sure you don’t scratch the dial or the hands.

Step 5

Measure the inside of the bezel

Measure the inside of the watch bezel with the Vernier caliper (make sure not to damage the dial). Because the regular acrylic crystals are kept in by tension, they must be somewhat more significant than the inside of the bezel. Add 0.2 mm to the measurement after rounding it to the nearest even number.

Let’s pretend you’re 29.76 mm tall. This is rounded to 29.8 mm, and then 0.2 mm is added. You’ll need a crystal with a value of 30.0. I always get a size up just in case. This may be useful, especially if the beginning dimensions are in the middle of two sizes.

Step 6

Use the crystal base

Loosen the crystal base screw to open the sliding metal plates. Close the plates with the new crystal in between, but not too firmly. Screw the crystal down to secure it in place.

Open the jaws of the crystal lift and position them over the crystal, resting on the metal plates. Slowly tighten the crystal lift until it starts to keep the crystal in place.

Examine your grip from every angle to see if it’s even. Because the crystal must be crushed to fit inside the bezel, tighten the crystal lift a bit more.

Step 7

Fit the new crystal

While maintaining the crystal above the watch, lower the crystal lift. The crystal should fall into the bezel with a bit of wiggle or spin.

If the crystal does not drop into the bezel, tighten the crystal lift even further.

Apply gentle downward pressure to unscrew the crystal lift slowly. Inside the bezel, the glass will expand and secure itself.

Step 8

Final Touch

Put the new crystal to the test. If the crystal has too much slack, you should go up a size if everything checks out; congratulations on a well-done job!

If you are watch is not severely damaged

If the glass on your watch is not seriously scratched, we may be able to offer you a quick fix repair in which we may remove the scratches without having to replace the face entirely. Polishing the watch glass often eliminates superficial scratches.

We utilize a specialized diamond paste, a mix of chemicals, and high-quality buffing equipment to remove a minimal quantity of glass and accompanying scuff.

While this procedure does not need as much labor as producing and replacing the glass, it does require the ability and knowledge to repair it effectively.

If not done correctly, the watch’s face may become uneven, and excessive pressure from buffing equipment may leave the glass’s surface more damaged and scuffed than before.

Additionally, extra caution should be exercised if the watch face, in particular, features a magnification cyclops bubble above the date display.

Some Additional Tips

Consider how much you paid for your watch and how much it will cost to replace the crystal, get it fixed, or buy a new watch. Consider purchasing a new watch if your current watch isn’t an antique, was passed down from a relative, or is excessively valuable.

Polish the crystal. All of Swatch’s watch crystals, for example, are laser sealed. Several retailers provide polishing services because the crystal on a Swatch cannot be removed. Many jewelry stores that sell timepieces have a buffer on hand or send the watch out for repair.

Important note about crystal watch glass replacement

Only the manufacturer, skilled horologist, or watch repair technician can change some crystals mechanically.

Please read the warranty before heading to the store where you bought your watch to ensure it includes crystal replacement. Always keep your timepiece’s instructions and schematics, especially the warranty information.
