What to know before buying
- Confirm that the watch is the 45mm size and that its back marking matches the listed compatibility. The maker limits water protection to daily surface exposure, advises drying the screen area after water exposure, and says not to combine the case with another screen protector. Customer feedback is mixed on water getting through, cracking, installation difficulty, and perceived value, so treat water resistance and durability claims as uncertain in practical use.
