All eyes were focused on the watch, but Apple CEO Tim Cook also unveiled a new MacBook and announced other deals at the company's event on March 9, 2015, in San Francisco.
Here are five things you need to know.
Apple calls it "the most personal Apple device ever." And potentially the most expensive.
Starts at $349 with Apple Watch Sport, aimed at fitness enthusiasts, in anodized aluminum in silver or space gray, with colorful band choices. Apple Watch stainless steel starts at $549, in traditional and space black. And for those who eat cake: Apple Watch Edition, an 18-karat yellow or rose gold version with a starting price of $10,000.
Includes: swipe-able "glances" that show you the information you use most; customizable faces for the dial of your choice, and lots of features for both fitness buffs and others who need a reminder to get out of their chairs.
"Taptic feedback" (a subtle tap) notifies wearers of new emails and other messages. By tapping a finger on the watchface, wearers can control music, send Instagram photos, sketch and send a dynamic drawing to a friend, and see who's calling. Return calls with voice or a voice-to-text messaging functionality.
Substitutes for: A hotel room key, boarding pass, even your wallet - Apple Pay promises to enable grocery-store checkouts with a single tap of your wrist.
"All-day" battery promises about 18 hours of life. Charge it by snapping a magnetic charger to the back of the watch.
Advance orders begin April 10. In-store sales start April 24 in the US, Australia, Canada, China, France, Germany, Hong Kong, Japan and Britain.
