Not to mention this variation on Apple Watch is equipped with a real-time depth gauge and delivers water temperature readings.Besides IP6X dust resistance and a flat sapphire crystal face, Apple Watch Ultra is EN13319 certified (for diving), and has been tested to comply with military standards (MIL-STD 810H).
