Despite the always-on screen, Apple is claiming the same 18-hour “all day” battery life as previous models. The power savings come thanks to a new low-power display driver, which might one day make it's way to other Apple devices.The Watch Series 5 adds a built-in compass that can discern which direction you're facing, just like the iPhone. In addition to heading, the Compass app can also show elevation, latitude, longitude, and even incline. That's great news for hikers looking to score some bragging rights. Was that climb really a 40-degree slope? Yes, yes it was.
Apple also showed off two new titanium models of the Watch, a light brushed style and a "space black" option. There's also a new ceramic model in glossy white. As with iPads, the aluminum models are now made of 100 percent recycled aluminum. The high-end Hermes-branded models are now also available in space black, and there are updated Nike models as well.The new Apple Watch starts at $399 for a Series 5 with GPS, and $499 with cellular. The new watches go on sale today, September 10, and they become available on September 20. The Series 3 Watch gets a price drop, down to only $199. The Watch Series 4 appears to have gone the way of the iPhone X; it wasn't mentioned during the launch event.
