|---|---|
| Size Confirmation | Measure your original clasp width before purchasing; select matching 9mm or 5mm size |

| Regular Inspection | Periodically check clasp closure tightness; replace if too loose |

| Aspect | Guidance |
|---|---|
| Daily Cleaning | Wipe the clasp surface with a soft cloth to remove sweat and dirt; use a soft toothbrush for crevices |
| Regular Inspection | Check clasp closure tightness and spring bar condition every 3-6 months |
| Looseness Treatment | If the clasp becomes loose, take it to a professional repair shop; DIY disassembly is not recommended |
| Rust Treatment | If rust appears, stop using immediately and replace to prevent watch loss due to detachment |
| Replacement Interval | Depending on usage frequency, clasps typically last 2-5 years; replace when noticeably loose or deformed |
