Apple to unveil iWatch alongside iPhone 6
The device is rumoured to feature a 2.5-inch arched rectangular display supplied by LG.
At next month's event, Apple is also expected to launch the iPhone 6, which will feature a larger 5.5in screen.
The iPhone 6, Apple's ninth iPhone model, is expected to be released in two different sizes - 4.7-inches and 5.5-inches - with the smaller of the two to be made available first.

Both versions are expected to use in-cell touch panel technology - built into the screen and allowing for thinner construction than with standard touch panel films - that was introduced with the iPhone 5.
Like its predecessor, the new model is expected to come in silver, gold and space grey.
The iPhone 6 will be powered by new operating system iOS 8, which Apple unveiled at its worlwide developers conference in June.
Through iOS 8, users will be able to monitor their health and fitness via HealthKit, which aggregates numerous healthcare and fitness apps, such as blood pressure and heart rate monitors through partners including Nike, and allows them to communicate with each other.

Users will be able to control home appliances and other connected devices through HomeKit, Apple's connected home framework. In a similar vein to HealthKit, this app will streamline your smart devices to control them in one place. One method of control will be via Siri - for example, you could tell Siri you were 'going to bed', and it could dim the lights, lock your doors, close the garage door and set the thermostat.
With the introduction of both of these key features, it's likely the iPhone 6 will take on even more of a lifestyle device role, designed to streamline our lives and make everyday tasks easier and more efficiently executed.

Suppliers are believed to be preparing to produce up to 80m of the new handsets by the end of December, according to the Wall Street Journal.
A new iPad with a 12.9-inch screen is also expected to go into production early next year, as the company looks to revamp its product range after announcing mixed third-quarter results in July.
