Apple's WatchOS software, although designed from the ground up, is oddly familiar but still takes a little while to get used to.
Our first few hours with the smartwatch were a nightmare - we'd swipe the screen when we should have pressed, changed the watch face while trying to check Twitter and, well, you get the idea. After a while, however, we soon became comfortable using the software - and while a little irritating and clunky to navigate at times, the Digital Crown makes it much more pleasant to do so than on an Android Wear device, for example.
While familiar - with its drag down Notifications bar, for example - the app homescreen is different to the software you'll find on an iPhone or iPad, for example, with Apple having designed WatchOS from scratch in order to better utilise the small screen.
For example, there's a pint-sized version of Apple's Messages app. Messaging on the Apple Watch is a little fiddly, and we've so far responded to most we've received on our wrist with the phrase 'Absolutely', one of Apple's pre-installed quick replies.
However, the Messages app is more intelligent than we initially gave it credit for, as it intelligently works out what a message you have received is asking. For example, somebody texts you asking whether you want fish or chips, it will bring up 'Fish', 'Chips' or 'Not sure' as your options.
Of course, Siri is also an option, and the voice dictation accuracy really is impressive, getting the right message nearly every time.
You'll find other standard Apple apps onboard too, such as Passbook, Calendar, a Knightrider-style Phone app and Maps, which uses the Taptic Engine under the hood to buzz your wrist when you need to turn a corner, a feature that has caused us to ditch the iPhone alternative for navigating around London.
There are some new ones, too. The Activty app has proved an early favourite, with the onboard fitness features among the best of the WatchOS software.
While we're not so keen on the Apple Watch prompting us to stand up when we're busy at work, the smartwatch - much like many others on the market - will record your excercise, calories burnt and heart rate, using the built-in sensor on its rear. We found the readings to be impressively accurate, more so than those we've seen on other wearable devices.
There's plenty of third-party apps already available for the Apple Watch, too. Twitter, for example, offers you a teeny wrist-worn version of your Timeline, Instagram a shrunken-down feed of your friends' lunches and Uber lets you book a cab straight from the smartwatch.
One bad thing about the Apple Watch's software, for now at least, is that it must be connected to an iPhone in order to properly function, meaning you won't receive Messages if you pop outside and leave your phone on your desk, for example.
However, Apple will rectify this with WatchOS 2.0, which will be rolled out to the wearable later this year.
One of the better things about it is Glances, which are accessible by swiping up from the Watch Face. There are a number to choose from, essentially a stream of widgets pulled in from Watch apps. Glances allow you to easily check your heart rate, have a quick look at what's trending on Twitter or 'glance' at the weather forecast before you leave the office.
Performance and battery life
Under the hood, the Apple Watch packs Apple's own S1 processor, and we've noticed no issues in terms of swiping through screens or firing open apps, impressive for a first-generation product.
We've yet to put the Apple Watch fully through its paces, but battery life has so far been much better than our admittedly low expectations. After a day of using it perhaps far too much, the Apple Watch has used around half of its battery, meaning those using the device more casually will likely get two to three days' use out of the device.
We'll update this review when we've tested the battery fully.
The Apple Watch, though not without its flaws, is undoubtedly the best smartwatch we've tested to date. Apple's approach for the device to be be as much about fashion as functionality pays off.
However, while it trumps its Android Wear rivals, we're still not convinced it's worth the hefty price tag, and we'd definitely consider the device a luxury rather than a must-have gadget - especially given the Apple Watch's current lack of support for native third-party apps.
