Cartier watches typically come with one of three case back types: snap-on, screw-down, or secured with screws. Understanding the type of case back your watch has is crucial before attempting to open it.

  • Snap-On Case Back: These are thin and press-fitted onto the case. They require careful prying to avoid bending or scratching.
  • Screw-Down Case Back: These have notches around the perimeter and require a case back wrench to unscrew.
  • Screwed Case Back: Small screws hold the back in place and must be removed with precision screwdrivers.
Case Back Type Opening Tool Key Considerations
Snap-On Case Knife or Pry Tool Work gently at the notch or seam to avoid damage
Screw-Down Case Back Wrench Align wrench precisely with notches; avoid slipping
Screwed Precision Screwdrivers Use correct size screwdriver to prevent stripping screws

When handling screw-down and screwed case backs, it is vital to maintain a steady hand and work on a stable surface to prevent slips that can cause scratches or internal damage.

Step-by-Step Procedure to Open a Cartier Watch Case

Once the case back type is identified and the appropriate tools are gathered, follow these steps to open your Cartier watch safely:

  • Prepare the Work Area: Work on a clean, well-lit surface with a soft cloth or pad to protect the watch.
  • Secure the Watch: Place the watch face-down, ensuring it is stable and will not move during the process.
  • Identify Opening Points: Locate any notches, screws, or seams around the case back.
  • Use the Correct Tool:
  • For snap-on backs, gently insert the case knife into the notch and carefully twist to lift the back.
  • For screw-down backs, fit the case back wrench into the notches and turn counterclockwise slowly.
  • For screwed backs, unscrew each screw evenly and store them safely.
  • Remove the Case Back: Once loosened, lift the case back carefully to avoid touching the movement or gasket.
  • Inspect the Gasket: Check the rubber gasket for wear or damage, as it ensures water resistance.

Avoid forcing the case back open, as excessive pressure may damage the watch or compromise its water resistance.

Precautions to Take When Opening a Cartier Watch

Due to the luxury and precision engineering of Cartier watches, taking precautions is essential to preserve their value and functionality:

  • Avoid Excessive Force: Cartier watches have delicate components; forcing the case back can result in irreversible damage.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
