Apple Watch Ultra 3 has satellite connectivity and larger display

Here is a 200-word summary of the news article: Apple has unveiled the latest iteration of its rugged Apple Watch Ultra, the Ultra 3. The most notable new feature is the addition of satellite connectivity, allowing users to access emergency services and share their location even in remote areas without cellular coverage. The Watch Ultra 3 is equipped with a 5G modem and can communicate directly with satellites, enabling features like Emergency SOS and Find My. The new model also features a larger display, with the "largest screen of any Apple Watch ever" and improved viewing angles thanks to the use of LTPO3 display technology. Battery life has also been significantly improved, with the device lasting up to 42 hours on a single charge, and up to 72 hours in low power mode. Other software updates include new health-focused features, such as hypertension alerts and a sleep tracking "Sleep Score" function. The design of the Watch Ultra 3 has been refined, with a 3D-printed case and slimmer display bezels. While Apple typically updates its watch lineup annually, the Ultra line has been on a two-year cycle. The company explains that the focus in the previous cycle was on redesigning the regular Watch models, leaving little reason to overhaul the Ultra.
