"Apple Watch SE combines elements of the Series 6 design with the most essential features of Apple Watch, all at a more affordable price," said Jeff Williams, Apple's chief operating officer.

Apple Watch SE features the same accelerometer, gyroscope, and always-on altimeter as Apple Watch Series 6, and with the latest motion sensors and microphone. It offers robust health and safety capabilities including fall detection, Emergency SOS, international emergency calling, and the Noise app, the company said.

With the S5 System in Package (SiP) and a dual-core processor, Apple Watch SE features a Retina display that is 30 percent larger than Series 3, according to Apple.

The Apple Watch SE is made of 100 percent recycled aluminum, and compatible with Apple Watch bands, the company said.

Starting at $279, Apple Watch SE will be available on Friday, Sept 18, in three case finishes.
