Back in the day (back before I was born, which was over 3 decades ago now), divers' watches were used to help divers swim underwater and keep track of their time under the surface. Divers' watches had to have some tough water resistance, since divers would find themselves going as deep as the eye could see (if not deeper). Today's water resistance for smartwatches is limited to IP67 and IP68 ratings, with 5-10 feet (1.5-3 meters) of water being the usual limit to water protection. The Moto 360, for example, has IP67 water and dust resistance, as does the first-gen. LG Watch Urbane, Fossil Q Founder, though the Android Wear-powered Casio WSD-F10 has 50-meter water resistance -- exceptional for a smartwatch. Water resistance has been Casio's strong suit for a long time now.
And yet, there are luxury watches out there from manufacturers that provides water resistance to 165 meters -- which is practically waterproof, though not technically waterproof. The reason behind the high estimation placed on the 165-meter limit is that most consumers will not find themselves going any further in the water than 165 meters (slightly over 900 feet), In fact, most consumers will not go anywhere near breaking that kind of water resistance, save scuba divers, underwater lovers, and professional divers who do it for a career.
If you're an Apple Watch owner who wants to take your wrist wearable swimming, or place your watch in the water at the beach for an unspecified amount of time, then the Catalyst Case for Apple Watch is just the accessory you need. It features water resistance to 165 feet (not meters; 165 feet = 50 meters), which far beyond the depth of most swimming pools and lakes. Unless you have a marine profession (water, that is), 165 feet water resistance is "practically" water-resistant.
The one drawback to the Catalyst Case for Apple Watch is that it takes some time to set up, which may be a turnoff for some who want a simple, three-step process to get the case up and running on your Apple Watch. The company recommends that you test the waterproofing before using it on your Apple Watch. You can take a look at the Catalyst Case and its setup on the Apple Watch by watching the video below.
