Early Tests Validate Apple Watch Ultra 3 and SE 3, Flag 5G and Satellite Limits

Reviews confirm battery gains plus new health tools, with regional support still patchy.

Overview

  • Both models have been on sale since September 19, priced at €899 for Ultra 3 and from €269 for SE 3 (€319 for cellular).
  • Independent testing reports roughly three days of battery life for Ultra 3 and about one day for SE 3, exceeding Apple’s stated estimates in typical use.
  • 5G connectivity uses RedCap on both watches, with access in Germany currently restricted to Deutsche Telekom tariffs.
  • Ultra 3 supports satellite-based emergency help, though EU activation for sending messages to personal contacts has not been fully enabled.
  • Ultra 3 adds a sleep index and blood-pressure warnings, while SE 3 gains sleep apnoea detection and the Vitals app but still lacks an ECG and the blood-pressure alert.
