Locating and Accessing the Stem Release Mechanism

Before attempting to remove the watch stem and crown, it is essential to locate the stem release mechanism within the watch movement. This mechanism is designed to securely hold the stem while allowing for its removal during servicing or replacement. Depending on the watch model and movement type, the stem release can be a small button, lever, or screw located near the stem’s insertion point.

To access the stem release:

  • Remove the watch case back using the appropriate tool, ensuring the movement is exposed without damage.
  • Identify the stem insertion area, usually on the side of the movement where the crown protrudes.
  • Look for a small recessed button, lever, or screw close to the stem. This is typically the release mechanism.

Handle the movement carefully to avoid dislodging or damaging other components during this process.

Techniques for Releasing the Stem

Once the stem release mechanism has been identified, the stem can be removed by applying the correct technique based on the mechanism type. The most common types are:

  • Push Button Release: A small button that must be pressed gently inward.
  • Lever Release: A tiny lever that needs to be lifted or slid.
  • Screw Release: A screw that must be loosened slightly without fully unscrewing.

Use fine watchmaker’s tools such as a pegwood stick, a small screwdriver, or a pusher tool designed for this purpose. Applying excessive force can damage the mechanism or the stem itself.

When pressing or moving the release mechanism, simultaneously pull the crown outward gently to slide the stem out of the movement.

Step-by-Step Process to Remove the Stem and Crown

The removal procedure can be summarized in these detailed steps:

  • Remove the watch case back to expose the movement.
  • Locate the stem release mechanism near the crown’s entry point.
  • Using a fine tool, engage the release mechanism (press button, lift lever, or loosen screw).
  • While holding the release mechanism, gently pull the crown and stem outward from the movement.
  • Once free, inspect the stem and crown for any wear or damage before proceeding with repairs or replacements.
