FAQs: Understanding Your Catalyst Apple Watch Case

Q: What makes your "Total Protection" case truly 100m/330ft waterproof when others are not?

A: It comes down to our obsession with precision engineering and patented technology. While other brands offer simple "water-resistant" shells, our Total Protection case is a fully sealed system. For newer models like the Series 9/8/7, we developed a revolutionary design:
  • A precision-molded silicone wrap creates a perfect seal around the screen and the back of the watch.
  • This wrap is then locked into place by a rigid polycarbonate frame, creating a watertight enclosure.
  • This allows the screen to remain exposed for perfect touch sensitivity and the back to be open for flawless ECG and heart rate sensor functionality, all while being completely sealed from the elements. It's a level of engineering that no other brand has been able to replicate.

Q: How can the case be fully sealed but still allow the heart rate sensor and ECG to work?

A: This is our key innovation. For older models (Series 6 and earlier), we used a thin, flexible membrane on the back that allowed sensor data to pass through. For the newer models (Series 7 and later), our patented silicone wrap creates a perfect, custom gasket around the exposed back of the watch. This means there is nothing between the watch's sensors and your skin, guaranteeing 100% accuracy for all health functions, including ECG, while the case remains completely waterproof around it.

Q: I've had other cases pop off my watch on impact. How does Catalyst prevent this?

A: We believe a case is useless if it doesn't stay on your wrist. That's why we don't sell simple "bumpers" that can pop off. Every Catalyst case is a fully integrated system that includes our comfortable and durable silicone watch band. The case is securely attached to the band, ensuring that it will never come off your wrist, no matter the impact.

Q: Can I use a screen protector with my Catalyst Apple Watch case?

A: Yes. Our cases are designed to be fully compatible with most screen protectors, including our own flexible PET screen protector. The precision fit of our case ensures that it will not nudge, peel, or interfere with a properly installed screen protector, giving you an optional extra layer of scratch defense.

Q: Are the cases easy to clean and disinfect?

A: Absolutely. Both our Total Protection and Rugged cases are designed to be washed with soap and water. They are also fully compatible with most EPA-approved disinfectants, including 70% isopropyl alcohol. This makes them ideal for healthcare professionals, athletes, or anyone who needs to keep their gear clean and sanitized.
