  • Loupe or magnifying glass: To closely inspect small components.
  • Rodico or similar cleaning putty: To gently clean and handle parts without leaving residue.
  • Stem release tool or pin: Some watches require pressing a tiny button or lever to release the stem.

Before starting, ensure you work in a clean, dust-free environment with adequate lighting.

Step-by-Step Procedure to Remove the Crown

Begin by removing the watch strap or bracelet if it obstructs access to the case back or crown. Next, open the case back carefully using the appropriate case back opener. Depending on the watch, this might be a screw-down case back or a snap-on type.

Once the movement is accessible, locate the stem release mechanism. This is often a small button, lever, or screw near the crown stem. Pressing or loosening this release will allow the crown and stem to be pulled out gently.

Key points to remember during the procedure:

  • Do not force the crown or stem out; resistance indicates the release mechanism is not fully disengaged.
  • Use minimal pressure when pressing the release button or lever.
  • Handle the movement delicately to avoid shifting or damaging other components.
  • Keep track of any screws or small parts removed during the process.

After the crown is removed, store it safely if it will be reused or replaced.

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.
