Apple has launched bigger iPhone 6 models, with screen sizes of up to 5.5 inches, and also unveiled its first watch.
The new phones are a significant upgrade from the outgoing flagship, the iPhone 5S, which has a 4-inch screen.
The watch – called simply Apple Watch – is customisable in “millions” of ways, said the firm at its annual showpiece event in California.
The company says the watch is a health and fitness device with many of the same features as a smartphone – but crucially needs an accompanying iPhone to work.
It uses GPS and Wi-Fi to track the distance covered by the wearer for example, and a tap of the screen can send an alert vibration to another Watch user.
It will start at $349 (£216) and comes out early next year.
Among the features of the two new iPhones are a better sensor and autofocus for the camera, and a landscape mode.
A HD FaceTime camera also promises improved face detection.
The iPhone 6 comes with a 4.7-inch screen, while the 6 Plus has a 5.5-inch display.
A new payment process called Apple Pay was also announced. It uses fingerprint ID for security and stores payment information on a NFC chip.
Apple claims the feature is more secure than keeping cards in a wallet.
Payments using NFC (near-field communication) technology could be “revolutionised” if Apple’s feature catches on, says one expert.
The phones go on sale in the US and eight other countries on September 19. Pricing is still to be announced.
Apple had been under pressure to make a bigger iPhone after rivals outgunned it with handsets like Samsung’s Galaxy S5 and the HTC One M8.
The Cupertino firm is also not the first tech giant to launch a watch product – Samsung brought out its Gear smartwatch in September 2013.
Google has also plunged headfirst into the trend for wearable technology with its Glass product.
