Our new impact protection case has not just evolved, it has totally been re-thought for the new Series 4 Apple Watch. The case still offers 9.9ft (3m) of drop protection through our dual-layer construction incorporating our innovative truss cushioning system. This case is built with raised bezels to keep important watch components – the display, heartrate sensors, and digital crown – fully exposed yet fully protected from bumps, knocks and drops. This new case features an integrated watch band, creating a total package of protection and style at a great price.
Speaking of style, the case is thinner than the apple watch itself, making the whole package super sleek. Watch band customization is easy through a quick release spring bar, compatible with Catalyst’s wide selection of sport bands or any other 22mm watch band with a watch pin connector.
The case is also super easy to install: simply clip the case onto the watch and you’re ready for action. Our new impact protection case keeps your Apple Watch stylish and secure on everyday urban adventures.
