Apple Watch 42MM waterproof case by Catalyst This Apple Watch waterproof case is amazing! I bought two but needed one. However...this case prevents water from getting in when swimming, diving and or playing in sand (beaches, dune buggying, etc). Best waterproof case out there. Great for your Apple Watch 42MM size. Only secure waterproof case available for the Apple Watch Series 1. Catalyst Accessories Watches
The way the design could be improved is it if was waterproof. The design is water resistant but it would really be a useful tool if the whole watch was waterproof in which people can really wear it at all times during their everyday lives.
