Screw-back watch backs are the most common type, and they are held in place by several small screws. Snap-back watch backs are held in place by a metal ring that snaps into place. Bayonet-back watch backs are held in place by a bayonet-type fitting that locks into place. Once you have identified the type of watch back that you have, you can then choose the appropriate watch case opener to remove it.

To remove a screw-back watch back, you will need a watch case opener that has a set of small screwdrivers. The screwdrivers should be small enough to fit into the slots on the watch back screws. Once you have the appropriate screwdriver, you can then carefully unscrew the screws that are holding the watch back in place. Once the screws are removed, you can then gently pry the watch back off of the watch case. To remove a snap-back watch back, you will need a watch case opener that has a set of snap-back pliers. The snap-back pliers should be placed on the metal ring that is holding the watch back in place. Once the snap-back pliers are in place, you can then carefully pry the metal ring off of the watch case. This will release the watch back and allow you to remove it from the watch case. To remove a bayonet-back watch back, you will need a watch case opener that has a bayonet-type fitting. The bayonet-type fitting should be placed on the bayonet-type fitting on the watch back. Once the bayonet-type fitting is in place, you can then carefully twist the watch back off of the watch case.

Preparation Before Starting

Before you begin the process of removing the back of a wristwatch, it is crucial to take the necessary preparatory steps to ensure a successful and safe procedure. Here’s a comprehensive guide to prepare before starting:

Gather Essential Tools and Materials

The first step is to gather the necessary tools and materials. You will need the following:

  • Watchmaker’s knife or case opener: A specialized tool designed to safely remove watch backs.
  • Caseback press: A device used to press the watch back back into place after removing it.
  • Microfiber cloth: To clean the watch and tools.
  • Gloves: To protect your hands and the watch.
  • Magnifying glass or loupe: To inspect small parts and ensure precision.
  • Small bowl or container: To hold loose screws or parts for safekeeping.
  • Toothpicks or tweezers: To remove dust or debris from the watch.

Properly Position and Secure the Watch

It is essential to position and secure the watch correctly before removing the back. This will prevent it from slipping or being damaged during the process. Here’s how:

  • Use a watchmaker’s case holder: This device securely holds the watch in place, allowing for precise and stable work.
  • Place the watch in a vice with padded jaws: Ensure that the vice is gently tightened to prevent scratching or damaging the watch.
  • Secure the watch with tape: Carefully tape the watch to a stable surface, such as a workbench or table.

Identify the Type of Watch Back

Before attempting to remove the back, identify the type of watch back the watch has. Common types include:

Type Description
Screw-back Held in place by screws around the perimeter of the watch case.
Snap-back Held in place by friction and pops into place with a press.
Bayonet-back Uses a bayonet-style locking mechanism to secure the back onto the case.

Identify the Type of Back

The first step is to identify the type of back your wristwatch has. There are three main types of watch backs:

  1. Snap-on backs are the most common type. They are held in place by a ring that snaps into a groove on the watch case.
  2. Screw-on backs are held in place by screws. They are more secure than snap-on backs, but they can be more difficult to remove.
  3. Bayonet backs are held in place by a bayonet-style fitting. They are less common than the other two types of backs, but they are very secure.

To identify the type of back your watch has, look at the edge of the case. If you see a groove, you have a snap-on back. If you see screws, you have a screw-on back. If you see a bayonet-style fitting, you have a bayonet back.

Remove the Back

Once you have identified the type of back your wristwatch has, you can remove it.

Snap-on Backs

To remove a snap-on back, use a watchmaker’s knife or a thin, flat object. Insert the knife or object into the groove on the edge of the case and gently pry the back off. Be careful not to damage the back or the watch case.

Screw-on Backs

To remove a screw-on back, you will need a small screwdriver. Unscrew the screws that are holding the back in place. Be careful not to strip the screws.

Bayonet Backs

To remove a bayonet back, use a watchmaker’s knife or a thin, flat object. Insert the knife or object into the slot on the edge of the case and gently pry the back off. Be careful not to damage the back or the watch case.

Back Type Removal Method
Snap-on Pry off with watchmaker’s knife or thin, flat object
Screw-on Unscrew with small screwdriver
Bayonet Pry off with watchmaker’s knife or thin, flat object

Proper Tools and Materials

To perform the watch disassembly safely and efficiently, you will need the following tools and materials:

Case Back Opener

This specialized tool is designed to fit the specific notches or grooves found on the watch’s case back. It applies leverage to the back by using adjustable tines that engage with the notches.

Case Wrench or Spanner

A case wrench or spanner is a specialized tool with a cylindrical head and adjustable jaws, used to grip and loosen or tighten the watch’s case back. It provides better grip and control compared to other tools.

Case Knife or Scalpel

A case knife or scalpel is a thin, sharp blade used to gently pry open the case back when there are no notches or grooves for a case back opener. It should be used with caution to avoid scratching or damaging the watch.

Microfiber Cloth

A microfiber cloth is used to clean the watch surfaces and remove any dirt or debris before opening. It helps prevent scratches and ensures a clean work environment.
