Opening an antique Elgin pocket watch requires careful handling and an understanding of its case type to prevent damage. The most common methods involve either unscrewing the back or gently prying it open.
Understanding Your Elgin Pocket Watch Case Type
Before attempting to open your watch, it's essential to identify whether it has a screw-back or a snap-back case. Applying the wrong technique can easily damage the watch.
Identifying Case Types:
- Screw-Back Cases: These cases typically have fine threads and appear to have no visible seam or notch for prying. The entire back cover will rotate to open. The edges of the back might have small, flat indentations or a knurled finish designed for grip.
- Snap-Back Cases: These cases usually feature a very thin seam where the back meets the main case, often with a small, almost invisible notch or lip along the edge. This notch is the insertion point for a case knife to pry the back off.
A good visual inspection, perhaps with a magnifying loupe, can help you determine the case style. You can find more details on identifying case types through resources like the National Association of Watch & Clock Collectors (NAWCC).
Opening a Screw-Back Elgin Pocket Watch
For an Elgin pocket watch with a screw-back case, the primary method is to carefully turn the back cover counter-clockwise.
- Positioning: Hold the watch firmly in one hand, perhaps resting it on a soft cloth or pad to prevent scratching.
- Application of Pressure: Use the palm of your other hand to apply steady, gentle turning pressure to the back cover. It's crucial not to press down too hard on the watch body itself, as this can actually tighten the back cover against the case, making it much harder to remove. The key is consistent, rotational, counter-clockwise pressure to loosen the threading and open the case.
- Even Rotation: Ensure your hand covers as much of the back as possible to distribute pressure evenly.
- Stubborn Cases: If the back is very tight or has been sealed for a long time, you might need a specialized tool:
- Rubber Ball: A sticky rubber friction ball can provide a better grip for your palm, allowing you to apply more rotational force without slipping.
- Case Wrench: For extremely stubborn cases, an adjustable watch case wrench can be used. These tools fit into the small indentations on the case back and provide leverage. Exercise extreme caution and minimal force to avoid scratching or deforming the case.
Practical Tips for Screw-Backs:
- Cleanliness: Ensure the watch and your hands are clean and dry to get the best grip.
- Soft Surface: Always work over a soft, clean surface to cushion the watch if it slips.
- Closing: When closing, carefully align the threads and turn clockwise until snug, but avoid overtightening.
Opening a Snap-Back Elgin Pocket Watch
For a snap-back case, you'll need a specialized tool to gently pry open the back.
- Locate the Notch: Carefully inspect the seam where the back cover meets the watch case. You should find a tiny notch, lip, or indentation designed for a tool. This is often near the pendant or at the 6 o'clock position.
- Select Your Tool: Use a dedicated watch case knife or a very thin, blunt, non-marring tool (like a plastic case opener). Avoid using sharp metal objects, as they can easily scratch or damage the delicate case.
- Gentle Insertion: Gently insert the tip of your case knife into the notch. The tool should fit snugly without forcing it.
- Leverage and Pry: With steady, gentle pressure, twist or pry the tool slightly. You should feel or hear a small "snap" as the back cover disengages. Work slowly around the edge if necessary, but typically, one point of leverage is enough.
- Remove the Back: Once disengaged, lift the back cover straight off.
Cautions for Snap-Backs:
- Avoid Force: Never force the tool. If it doesn't open easily, re-examine the case for another notch or try a different angle.
- Protect the Case: Place a piece of watchmaker's tape or a thin cloth over the case edge near the notch to protect against accidental scratches from the tool.
- Closing: When replacing, align the back cover carefully and apply even pressure with both thumbs around the edges until it snaps securely into place.
Essential Tools for Opening Your Pocket Watch
Having the right tools is paramount for safely opening your antique Elgin pocket watch.
| Tool Type | Description | Use Case |
|---|---|---|
| Rubber Ball/Grip | A soft, tacky rubber ball or pad designed for friction grip. | Safely unscrewing tight screw-back cases without scratching. |
| Watch Case Wrench | Adjustable, multi-pronged tool with blades or pins to engage case back grooves. | For very stubborn screw-back cases, offering more leverage. |
| Watch Case Knife | A thin, hardened steel blade with a finely blunted edge. | Prying open snap-back cases at the designated notch. |
| Plastic Case Opener | A non-marring plastic tool, similar in function to a case knife. | A safer alternative to metal case knives for snap-back cases. |
| Watchmaker's Loupe | A magnifying lens for close inspection. | Identifying case type, locating notches, inspecting for damage. |
| Dust Blower | A rubber bulb that provides a puff of air. | Removing dust and debris before and after opening the case. |
You can find these tools at specialized watchmaking supply stores or online retailers that cater to horology enthusiasts, such as Esslinger.com or similar reputable suppliers.
General Precautions When Handling Your Antique Watch
- Clean Workspace: Always work on a clean, well-lit surface, preferably covered with a soft, lint-free cloth or mat to prevent scratches and to catch any small parts.
- Gloves: Consider wearing clean, non-powdered finger cots or nitrile gloves to avoid transferring oils and fingerprints to the watch movement or case.
- Avoid Dust and Moisture: Work in a dry, dust-free environment. Keep the watch open for the minimum time necessary to prevent dust and moisture from entering the movement.
- Know Your Limits: If you encounter significant resistance, are unsure about the case type, or lack the proper tools, it is always best to consult a professional watchmaker. Forcing an antique watch open can cause irreversible damage.
