Methods for Opening Different Types of Fob Watches

Fob watches come in various styles and designs, each requiring a specific approach to open the case safely without causing damage. Understanding the type of case your fob watch has is crucial before attempting to open it.

The most common fob watch case types include snap-back, screw-back, hinged, and bezel types. Each has distinct features and methods for opening:

  • Snap-back cases: These have a smooth back that snaps onto the watch body. They usually have a small lip or notch where a case knife can be inserted.
  • Screw-back cases: Featuring small indentations or grooves around the edge, these require a specialized case wrench to unscrew the back.
  • Hinged cases: These open like a locket, with a visible hinge on one side.
  • Bezel-opening cases: The bezel (the ring surrounding the crystal) can sometimes be twisted or popped off to access the movement.

When handling any fob watch, ensure you work on a soft, clean surface and use appropriate tools to prevent scratches or other damage.

Step-by-Step Guide for Opening a Snap-Back Fob Watch

Snap-back cases are among the most common and are relatively straightforward to open if handled carefully.

  • Place the watch face down on a soft cloth to avoid scratching the crystal.
  • Locate the small notch or lip on the edge of the case back.
  • Hold the case knife firmly and insert the blade gently into the notch.

  • Once opened, avoid touching the movement directly with your fingers; use tweezers if necessary.

Step-by-Step Guide for Opening a Screw-Back Fob Watch

Screw-back cases require a different approach due to their threaded design.

  • Lay the watch face down on a non-slip surface.
  • Select the appropriate size pins on the case wrench to fit into the notches or grooves on the back cover.
  • Adjust the wrench for a snug fit, ensuring all pins are securely engaged.
  • Turn the wrench counterclockwise to unscrew the back. If the back is too tight:
  • Use a rubber ball with firm pressure to try unscrewing it by hand.

  • Once loose, finish unscrewing by hand and lift off the back cover.

Opening Hinged and Bezel Fob Watches

Hinged cases open like a small door or locket, allowing easy access to the interior. To open:

  • Locate the hinge, usually visible on one side of the back cover.
  • Find the small lip or indentation opposite the hinge.
  • Use a fingernail or a case knife to gently pry open the cover.
  • Avoid forcing the cover to prevent bending the hinge or the cover itself.

For bezel-opening fob watches:

  • Examine the bezel for any signs it can be twisted or popped off.
  • Use a bezel remover tool or gently twist the bezel counterclockwise.
  • If bezel removal is difficult, avoid excessive force as it may damage the watch. Consult a professional if necessary.

Precautions and Tips When Opening a Fob Watch

Opening a fob watch requires patience and care. Keep the following points in mind to protect your timepiece:

  • Always work in a clean, dust-free environment to prevent debris from entering the watch.
  • Avoid using excessive force; if the case does not open easily, reconsider your approach or tools.
  • Use plastic or rubber tools where possible to reduce the risk of scratching.
  • Never touch the movement or internal parts with bare fingers; oils and dirt can damage delicate mechanisms.
  • If unsure or dealing with a valuable antique fob watch, consider professional assistance.

By following these guidelines and using the appropriate tools, opening a fob watch can be a manageable task while preserving the integrity of the piece.

Identifying the Type of Fob Watch Case

Before attempting to open a fob watch, it is essential to determine the type of case it has, as different designs require different methods for opening. Most fob watches fall into one of three categories: snap-back, screw-back, or hinged cases.

  • Snap-back cases: These cases have a back cover that snaps onto the case body. They often have a small lip or notch where a tool can be inserted to pry the cover open.
  • Screw-back cases: These feature a threaded back cover that screws onto the watch case. They typically require a case wrench or a specialized tool to unscrew the back.
  • Hinged cases: These have a back cover attached by a hinge, which opens like a small door. A small tab or lip is usually present to lift the cover.
Case Type Identification Method Opening Method
Snap-back Look for a small notch or lip on the back cover Use a thin blade or case knife to pry open
Screw-back Notice the presence of notches or grooves around the edge Use a case wrench or adjustable opener to unscrew
