Understanding Your Cartier Tank Watch
The Cartier Tank series includes various models with different designs, including the Tank Louis, Tank Solo, and Tank Americaine. Each model might have a slightly different method for opening. Understanding the type of back your specific model has is crucial. Cartier Tank watches typically feature either a screw-down back or a snap-on back.
General Steps to Open a Cartier Tank Watch
1. Prepare Your Workspace
Find a clean, well-lit workspace.
Lay out your tools and watch repair mat.
Ensure you are wearing anti-static gloves to avoid damaging any electronic components.
2. Inspect the Watch Case
Use the watchmaker’s loupe to examine the watch case for any visible screws or notches that indicate how the case back is attached.
Determine whether your watch has a screw-down back or a snap-on back.
3. Removing a Screw-Down Back
Locate the Screws:
If the watch has a screw-down back, you will see small screws securing the case back in place.
Use Precision Screwdrivers:
Select the appropriate size screwdriver for the screws.
Gently loosen and remove each screw, keeping them in a safe place for reassembly.
Remove the Case Back:
Once all screws are removed, use the watch case opener tool to gently pry off the case back. Be cautious not to scratch the watch or apply excessive force.
4. Removing a Snap-On Back
Find the Notch:
Look for a small notch or indentation along the edge of the case back. This is where you will insert the watch case opener tool.
Insert the Case Opener Tool:
Carefully insert the tool into the notch.
Gently twist or lever the tool to pop the case back off.
Pry the Back Off:
Once the back is slightly lifted, use tweezers to carefully remove it from the watch case.
Handling the Watch Movement
Once the case back is removed, you will have access to the watch movement.
Avoid touching any components inside the watch movement to prevent damage or contamination.
