What counts as a dive?
You can log almost any underwater activity—swimming below the surface at the local pool, diving down to explore a reef while snorkeling, or going on a scuba adventure.
Your dive is tracked under the following conditions:
You use the Depth app or a third-party app that supports underwater activity tracking.
Your depth exceeds 1 meter and you’re submerged for more than 5 seconds.
A logged dive can be a single dive, such as a scuba dive, or a series of dives that are aggregated together—for example, when you’ve submerged multiple times to work on your breath control at the pool.
Begin your dive
Use one of the following methods:
Manually: Before you go into the water, open the Depth app
.Action button: (supported on Apple Watch Ultra models) If you’ve set the Action button to Dive, press the Action button.
Automatically: If you turned on Auto-Launch, the Depth app starts tracking a dive when your depth exceeds 1 meter and you’re submerged for more than 5 seconds.
When submerged, the screen locks and Water Lock is turned on. In the Depth app, screen taps and Digital Crown presses don’t register. Third-party diving apps may allow you to interact with Apple Watch Ultra while underwater by turning the Digital Crown or pressing the Action button.
End a dive
After you surface, end the dive session and turn off Water Lock (which clears water from the speaker) with one of the following methods:
Manually: Press and hold the Digital Crown.
Action button: (available on Apple Watch Ultra models for dives longer than 3 minutes) If you’ve set the Action button to Dive, press the Action button to end the dive.
Automatically: The dive ends when Apple Watch has been out of the water for 10 minutes.
Note: If you descend again within 10 minutes, your time underwater is added to the previous time you were submerged and is logged as a single dive.
