Apple will open its new Watch wearable for online pre-orders on April 10 and start shipping the watch on April 25 to nine countries including Australia.
The device will come in three "collections" dubbed Watch Sport, Watch and the 18-carat yellow or rose gold Watch Edition. Watch Sport will retail for A$499 and $579, will the midrange Watch will sell for $799 to $1629 depending on model.
The gold Watch Edition will only be available in limited quantities and in select retail stores, starting at A$14,000 a piece.
Watch wearers will be able to make purchases on the device through Apple's Pay contactless payments system, however the solution still only remains available in the US.
Apple Watch will have up to 18 hours battery life, depending on usage. Unlike other smartwatches, there is no USB or similar port on the Apple Watch - it uses a snap-on magnetic MagSafe-style charger that attaches to the back of the device.
The watch communicates with iPhones and other compatible devices through Bluetooth and wi-fi. As long as the Apple Watch is regularly synced with an iPhone 5, 5c, 5s, 6 or 6 Plus running iOS 8.2 or later, the watch will keep time within 50 milli-seconds of coordinated universal time.
Users will be alerted to a notification via Apple's 'taptic engine', which delivers a tap sensation to the user's wrist.
Apple Watch allows a user to send messages, read email, play music and answer calls, as well use Apple's Passbook app, voice assistant Siri, and Maps mapping application. Watch users will also be able to access the Watch app store through the device to browse and download applications.
