Replacing aged or damaged case back gaskets on Cartier Ballon Bleu watches
Suitable for Ballon Bleu models with case diameters of 28mm, 33mm, 36mm, 42mm, etc.
Ensuring water resistance performance when reinstalling the case back during service
1. Is this a genuine Cartier gasket?
No. It is a compatible aftermarket replacement, not original, but precisely sized for Ballon Bleu models.
2. How do I choose the correct size for my watch?
Measure the inner groove diameter of your case back (or the outer diameter of the original gasket). Common Ballon Bleu case sizes: 28mm, 33mm, 36mm, 42mm. Consult the seller for size options.
3. Will the original water resistance be restored after installation?
Water resistance depends on the gasket, installation, and other seals (crown, pushers). With proper installation, everyday splash resistance (30-50m) can be restored. A water resistance test is recommended.
4. What should I pay attention to during installation?
Clean the groove and gasket before installation. Apply a small amount of silicone grease to the gasket. Press it evenly into the groove, then tighten the case back screws diagonally.
5. How often should the gasket be replaced?
Rubber gaskets age naturally. Replace every 2-3 years or whenever you notice hardening, cracks, or loss of elasticity during service.
