Its display screen adopts improved wide-angle OLED and LTPO3 technology, achieving the maximum display area of the Apple Watch series by reducing the border. In constant light mode, the refresh rate is increased to display the dynamic second hand.
In terms of communication functions, there has been a leap forward with the redesign of radios and antennas, doubling the signal strength, allowing users to connect to satellites 800 miles away from Earth for communication. In terms of battery life, there has been a significant improvement, with the Apple Watch Ultra 3 having a maximum battery life of 42 hours, which is a significant improvement compared to its predecessor and reduces the hassle of frequent charging for users, meeting the needs of long-term outdoor use.
In terms of material, the Apple Watch Ultra 3 is made with advanced 3D printing technology, using 100% recycled titanium metal, which ensures the watch's durability and responds to environmental protection concepts. The Apple Watch Ultra 3 is equipped with the largest Apple Watch display to date, providing users with a broader visual experience. Whether it's viewing maps, navigation, or browsing various information, it is clearer and more convenient.
