Introduction

This guide provides a detailed, step-by-step process for safely removing a winder (also known as the crown and stem) from a watch. Whether you’re performing routine maintenance, cleaning, or replacing a worn part, this guide will walk you through the process. It’s important to note that this process requires a delicate touch and the right tools. If you are not confident in your ability to perform these steps, it is always best to consult a professional watchmaker.

Safety First: Tools and Precautions

Before you begin, it’s crucial to have the right tools and take the necessary precautions to avoid damaging your watch.

Essential Tools:

• Watch Case Opener: The type will depend on the back of your watch (e.g., a friction ball for screw-down backs, a case knife for snap-on backs).
• Watchmaker’s Screwdriver Set: A set of fine-tipped screwdrivers is essential.
• Tweezers: For handling small parts.
• Loupe or Magnifying Glass: To see the small components of the watch movement clearly.
• A Clean, Well-Lit Workspace: A dust-free area is crucial to prevent contaminants from entering the watch movement.
• Soft Cloth or Watch Holder: To protect the watch crystal and case from scratches.

Precautions:

• Work in a clean environment: Dust and debris are the enemies of a watch movement.
• Be gentle: Watch components are delicate and can be easily damaged.
• Keep track of screws and small parts: Use a parts tray to keep everything organized.
• Never force anything: If a part doesn’t move easily, there’s likely a reason. Stop and reassess.

Step-by-Step Guide to Removing the Winder

Step 1: Open the Watch Case

The first step is to open the back of the watch to access the movement. The method for this will vary depending on your watch.

• Snap-on Case Backs: Look for a small lip or tab on the edge of the case back. Carefully insert a case knife and gently pry it open.
• Screw-down Case Backs: These will have notches around the edge. Use a friction ball or a Jaxa-style case back wrench to unscrew the back.

Step 2: Identify the Release Mechanism

With the case back removed, you’ll need to locate the mechanism that holds the stem in place. There are two common types:

1. Dimple/Push-Button Release: This is the most common mechanism on modern watches. Look for a small, recessed button or “dimple” near where the stem enters the movement.
2. Screw Release: Some older or specific types of movements use a small screw to hold the stem in place.

Step 3: Release the Stem

For Dimple/Push-Button Release:

1. Pull the crown out to the time-setting position (the furthest position from the case). In some cases, the crown should be pushed all the way in. If one doesn’t work, try the other.
2. Using a fine-tipped screwdriver or a pointed, non-sharp tool (like a toothpick), gently press down on the dimple.
3. While keeping the dimple pressed, gently pull the crown and stem out of the watch. It should slide out smoothly.

For Screw Release:

1. Locate the small screw near the stem.
2. Using a watchmaker’s screwdriver, turn the screw counter-clockwise one to one-and-a-half turns. Do not fully unscrew it, as this can cause other parts of the keyless works to disengage, which is a much more complicated repair.
3. Once the screw is loosened, the stem should be free. Gently pull the crown and stem out of the watch.

Reassembly

To reinsert the stem, simply reverse the process:

1. Gently guide the stem back into the movement. You may need to twist it slightly to get it to engage properly.
2. Once the stem is in place, it should click securely.
3. If you have a screw release, tighten the screw (but do not overtighten).
4. Test the functions of the crown (winding, setting the time, setting the date) to ensure everything is working correctly.
5. Carefully replace the case back, ensuring any gaskets are properly seated to maintain water resistance.
