Apple has introduced new Apple Watch cases and bands, available starting today, including new gold and rose gold aluminium Apple Watch Sport models. watchOS 2 — which arrives as a free update on September 16 — makes apps quicker and more fluid by running natively on Apple Watch, and introduces new watch faces, the ability for third-party apps to display information on the watch face as complications, and an innovative way to see future events, past headlines, and more with Time Travel. Apple Watch collections are expanding with new case colors and fresh new bands. With new standalone Sport Bands that range from rich vibrant colors to more neutral tones, Apple Watch is now more customizable than ever.
