Identifying the Stem Release Mechanism

The first step in removing a watch stem is to identify the type of stem release mechanism your watch uses. Most mechanical watches feature a small detent screw or lever that locks the stem in place within the movement. This mechanism prevents the stem from accidentally sliding out during regular use.

The stem release can typically be found near the crown wheel or the keyless works inside the movement. It is crucial to work under adequate lighting and use a loupe or magnifying glass to clearly see the delicate parts.

Common stem release types include:

  • Detent Screw: A tiny screw that, when loosened slightly, allows the stem to be pulled out.
  • Push-Button Lever: A small lever that must be depressed to free the stem.
  • Spring-Loaded Collar: Some watches use a spring that must be compressed to release the stem.

Understanding which mechanism your watch employs helps prevent damage during removal and guides the choice of tools needed for the procedure.

Preparing the Watch for Stem Removal

Before attempting to remove the stem, ensure you have the correct workspace and tools. A clean, dust-free environment with a soft cloth or watchmaker’s mat is ideal to protect the watch from scratches and debris.

Essential tools include:

  • Jeweler’s screwdriver set (especially precision sizes)
  • Tweezers with non-magnetic tips
  • Loupe or magnifier
  • Case opener (if necessary to access the movement)
  • Pegwood or toothpicks to gently manipulate parts

Steps for preparation:

  • Remove the watch case back carefully if the stem release mechanism is inside the movement.
  • Stabilize the movement to avoid shifting or damage when pressing or loosening the release.
  • Identify and mark the position of the crown and stem before removal to ensure proper reassembly.

Step-by-Step Process to Remove the Stem

Once the release mechanism is identified and the watch is properly prepared, follow these steps carefully:

  • Locate the Release Component: Using a loupe, find the detent screw or lever adjacent to the stem.
  • Loosen or Depress the Release:
  • For a detent screw, use an appropriate jeweler’s screwdriver to loosen it slightly (do not fully remove).
  • For a lever, gently press it inward with a pegwood stick or a fine tool.
  • Gently Pull the Stem Out: While holding the release component in its active position, slowly and evenly pull the crown outward. The stem should slide free without force.
  • Inspect the Stem and Movement: Check for any signs of damage or debris that could affect future operation.

If resistance is felt, stop and reassess to avoid breaking the stem or damaging the movement.

Locating and Identifying the Stem Release Mechanism

The stem release mechanism is a small component designed to securely hold the stem in place while allowing removal without damage. The exact location and design vary based on the watch caliber and manufacturer.

Common types of stem release mechanisms include:

Type Description Identification
Push-button release A small button or lever near the stem housing that must be pressed to free the stem. Look for a tiny protruding button adjacent to the stem tube.
Screw-release mechanism A tiny screw that, when loosened slightly, releases the stem. Locate a small screw near the stem tube, usually marked or distinct.
Detent lever A lever that must be gently lifted or moved to release the stem. Identify a lever close to the stem socket, often requiring magnification.

Using a loupe, carefully examine the movement near the stem tube to identify the type of release mechanism present.

Step-by-Step Procedure to Remove the Stem

Follow these steps meticulously to safely remove the stem from the watch movement:

  1. Set the crown to the correct position: Pull the crown gently to the time-setting position to relieve tension on the stem.
  2. Locate the release mechanism: Using magnification, identify whether it is a push-button, screw, or lever type.
  3. Release the stem:
