What happens when you dive too deep with the Apple Watch Ultra? I put it to the test to show you exactly how the Apple Watch Ultra 'Depth' app works, as well as how the data works behind the scenes. Dive on in! The first thing to know is the Apple Watch hardware design, which is certified to 100m in depth. And then the second is their software app, which is designed for usage to 40m (131ft) of depth. That native app is called…umm…Depth. And it essentially aims to show your current, well…depth (and duration/water temp). Meanwhile, there's the Huish Outdoors app called the Oceanic+. That app (which costs $79/year, but they also have day/month passes) has all the dive-related functions you’d find in a normal dive computer. Things like dive planning, water type, ascent warnings, safety stops, mixed gas options, etc… That app isn’t available today, and is slated for sometime this fall. If you check out the two specs that Apple certified against, ISO 22810:2010 specifies the waterproof rating for watches statically (to 100m in Apple’s case). However, DIN EN13319 covers the depth gauge and specifically operation of said gauge to the specified water pressure listed (100m in this case), given that would require pressing buttons in order to use said operation as covered under the functional area, thus would be covered to 100m according to Apple’s claims.
