Which Apple Watch models work with DiveOne

Apple Watch Series 10 and later, and every Apple Watch Ultra model including Ultra 3, have a depth sensor. On Series 10 and later it measures to 6 m. The Ultra sensor range is 40 m, which DiveOne does not use: DiveOne 1.0.2 records depth to 6 m on every supported watch. Models without a depth sensor, such as Series 9 and earlier and Apple Watch SE, are not supported.

Supported models also have a water temperature sensor. DiveOne records water temperature when the sensor reports a value. Older models do not measure water temperature.

Apple Watch Ultra is rated WR100, and its depth gauge is certified to EN 13319, the depth-gauge standard; that is not a dive computer certification. Series 10 and later are rated WR50, and Apple supports them for shallow water activities such as snorkeling, with depth readings to 6 m. Whatever your watch, DiveOne records to 6 m and is not a dive computer.

We list only watches that can record depth. A watch without a depth sensor could show surface time, but that would not be dive tracking, so DiveOne does not support it. We would rather support fewer devices honestly than more devices misleadingly.
