The Apple Watch Ultra 2 is no longer Apple's newest flagship, but it remains remarkably close to the Ultra 3. You still get the same rugged titanium build, solid battery life, a bright 3,000-nit display, and Apple's health-tracking features. For most users, the Ultra 2 delivers nearly the same experience for less.

Forward-looking: A team of physicists from Julius-Maximilians-Universität Würzburg in Germany have created the world's smallest pixel to date. Measuring just 300 by 300 nanometers, the tiny light source is just as bright as a conventional OLED pixel that's five by five micrometers in size and could eventually serve as the building blocking for next-generation, high-resolution wearable displays.
The first reviews of the Google Pixel Watch 4 are in, praising its expanded health and fitness tracking features, bright display, and two-day battery life. It's also more repairable than before, allowing users to swap the battery and display, all while keeping the same price.
