Use a new sealing gasket, apply UV adhesive, and press evenly with a crystal press. Clean the case groove. Professional installation is strongly recommended, followed by a water resistance test.
**4. Will the original 1220m water resistance be maintained?**
Proper installation with a new, correct gasket can restore similar water resistance. A pressure test is essential to verify.
