With the launch of the Apple Watch, the Cupertino has attempted to shake off long-running criticism that it has been keeping itself away from competition over wearable devices. The timepiece is slated to go on sale early next year for $349, but the technological limitations of Apple’s device raise questions as to whether the smartwatch segment will take off with consumers.

“Apple Watch is the most personal device we’ve ever created,” said Tim Cook, during the iPhone 6 Keynote. “An entirely new product. We believe this product will redefine what people expect from its category.”

The Apple Watch, which is available in two different sizes, 38mm and 42mm, has a square Retina display with curved down edges, Custom-designed S1 SiP chip, built-in speaker, and supports for Apple Pay and Siri.

Besides, the iPhone maker offers a range of watch straps that “include the Sport Band in black, blue, green, pink and white; the Classic Buckle in black and midnight blue; the Leather Loop in bright blue, light brown and stone; the Modern Buckle in midnight blue, brown, soft pink, rose gray and bright red; the Milanese Loop in stainless steel; and the Link Bracelet in brushed stainless steel and polished space black.”
