How will it work? Apple CEO Tim Cook is keen to assure that his team didn't want to create a boiled-down iPhone -- joking that there's no pinch-to-zoom, etc. In a similar way to how Samsung's Gear watches work, the Apple Watch knows when you lift your wrist to look at it, and activates the display (and shows you some apps). If you were wondering about how you'll charge it, it uses inductive charging, but actually uses something that looks quite a lot like a small MagSafe. Other rumored details that turned out to be true include the flexible display (that can apparently determine between a tap and a press), and a heart rate monitor.

Worried that you won't get along with a watch that everyone else also has? Apple has thought of that, and has created three watch "collections" called Apple Watch, Apple Watch Sport and Apple Watch Edition. The main differences being the finishes: aluminum, stainless steel and 18-karat gold (that's Edition)! There's a choice of two sizes also. The bad news is: You'll need an iPhone to go alongside it (the watch has WiFi and Bluetooth 4.0), whichever one you choose. Also, as you'd expect, Apple Watch does notifications, so you can see meetings and message alerts -- many of these are actionable too, so you can decline an invite without reaching for the phone. As we'd heard earlier in the week, there will be dedicated apps for the Apple Watch, both from third parties (American Airlines, City Mapper) and Apple (such as maps with navigation, etc.) -- described as "iOS-based."

What about fitness credentials? Yup, that's a big part of Apple Watch, too, with Cook stating: "It's a very important area for me, and important for Apple." What that really means is that it will act as a fitness tracker, and a dedicated sports watch, complete with "Activity" and "Workout" apps (but you'll need your iPhone's GPS for tracking a run -- BOO!). The activity apps do sound a little more than just a basic step counter though. For example, they'll use a mix of data from the watch (like your pulse) and your phone (for more detailed distance measuring), to build a more "complete" picture of your daily physical output. Expect even more apps, especially those from third parties to be announced between now and that ambiguous 2015 launch date.
