## 8. FAQ

### Q: Will a metal case affect the watch’s weight?

**A:** Yes, significantly. A metal case adds 20-40g depending on the model. Some prefer the substantial feel; others find it too heavy for daily wear.

### Q: Can I return to the original resin case?

**A:** Yes, if you kept all original parts. However, repeated disassembly risks damaging components.

### Q: Do metal cases void the Casio warranty?

**A:** Yes, modifications void the warranty. Keep original parts if you want to restore for warranty service.

### Q: Are metal cases as durable as original resin?

**A:** Metal is more scratch resistant but can dent. Resin absorbs impact better. For heavy-duty use, consider resin.

### Q: Which finish is most durable?

**A:** Brushed stainless steel hides scratches best. PVD/gunmetal coatings can wear at edges. Polished shows scratches but is easiest to refinish.
