Get a Depth and Water Seal Test for your Apple Watch Ultra
If you have an Apple Watch Ultra model and want to check that its depth gauge and seals work properly, you can get a Depth and Water Seal Test from Apple.
You might want to send your Apple Watch Ultra for a Depth and Water Seal Test if:
You'd like to check the functionality of the depth gauge in your Apple Watch Ultra.
You might have caused unseen damage to your Apple Watch Ultra — for example, by crashing while bicycling, or hitting your watch on a rock during a hike.
You should avoid diving with your Apple Watch Ultra if it has visible cracks on the front display or back crystal. Cracks in the display or crystal can allow water to enter and damage your watch, especially if it's subjected to high water pressure. For this same reason, the Depth and Water Seal Test can't be performed if your Apple Watch Ultra has visible cracks.
What happens during a Depth and Water Seal Test
The Depth and Water Seal Test determines whether your watch's depth gauge and seals are working properly at the time of the test.
First, we perform a visual inspection for any cracks or damage to the exterior of your Apple Watch Ultra. If your watch doesn't have any visible damage, we test its system water seals and depth gauge.
If your Apple Watch Ultra needs to be replaced
If your Apple Watch Ultra has unseen damage, the Depth and Water Seal Test may leave the watch inoperable and may result in a replacement fee if the device is not covered by the Limited Warranty, or by any applicable consumer protection laws or regulations.

WARNING: Apple Watch Ultra should be used only by trained divers for recreational dives of 130 feet (40 meters) or less. The Depth app on Apple Watch Ultra is not a dive computer and does not provide decompression stop information, gas analysis, or other recreational scuba diving functionality. Apple Watch Ultra is compatible with third-party apps that can function as a dive computer for recreational scuba diving to 130 feet (40 meters).
Underwater activities are risky. Always use a secondary depth gauge and timer/watch, as well as decompression tables. Always follow diving safety protocols and dive with a buddy. Check functionality regularly during a dive, and ascend safely if there is any apparent malfunction. There is always a risk of decompression sickness (DCS) with any dive. Seek immediate medical treatment if you think you may be experiencing DCS.
