The Apple Watch Ultra 4<\/a> arrives four years after the original model. Across three subsequent generations, Apple added a brighter and larger display, satellite connectivity, new health sensors, more capable chips, and longer battery life. For owners of the original Ultra, are those cumulative improvements enough to justify upgrading now, or can their existing watch last another year?<\/p>\n

Both watches retain a 49mm titanium case, an Action button, a siren, dual-frequency GPS, and support for recreational diving to 40 meters. The Apple Watch Ultra 4<\/a> starts at $799 in the U.S. Apple discontinued the original Ultra in 2023, and it no longer supports the latest major watchOS release. Here are the key differences between the two models:<\/p>\n

Existing first-generation Apple Watch Ultra owners can reasonably keep their watch for another year if its battery still covers their usual days and workouts. Losing support for \u200cwatchOS 27\u200c is significant, but it does not prevent the original Ultra from continuing to handle notifications, activity tracking, navigation, and its other existing features. Owners satisfied with those capabilities may prefer to eke out another year of use and wait to see whether next year’s model offers a more substantial upgrade.<\/p>\n

However, the Ultra 4 is a worthwhile upgrade for anyone already running into the original model’s limitations. The new Health Sensing System provides more detailed heart-rate and recovery insights, while sleep apnea and hypertension notifications expand its health capabilities. These changes are most compelling if you will use the additional information to follow changes in your daily condition or adjust your training.<\/p>\n

Longer battery life and satellite connectivity strengthen the case for owners who record extended workouts or regularly travel beyond cellular coverage. If your original Apple Watch Ultra now struggles to finish an outing without charging, the improved battery life is a practical reason to replace it. The larger, brighter display, newer gestures, Audio Intelligence, and expanded Precision Finding support also make the cumulative upgrade more noticeable in everyday use.<\/p>\n

Software support is a major reason to move on. The original Apple Watch Ultra cannot run watchOS 27<\/a>, so it misses \u200cSiri\u200c AI and the latest operating system’s other additions. If those features would materially improve how you use your watch, waiting another year means accepting those limitations in the meantime.<\/p>\n","protected":false},"excerpt":{"rendered":"The Apple Watch Ultra 4 arrives four years after the original model.
