According to Tech Crunch, sources familiar with the matter “confirmed” that Asus is planning to introduce an Android Wear smartwatch as soon as September. It’s said that Asus intends to sell the smartwatch for $99, or $149, thus positioning it as a significantly cheaper alternative to Samsung’s Gear Live and LG’s G Watch (which cost $199, and $229, respectively). Reportedly, the first Android Wear device from Asus will feature an AMOLED display. It may also come with gesture controls, though that hasn't been confirmed.
As for HTC, the company repeatedly mentioned that it would release wearable devices this year, and one of them will almost certainly run Android Wear. The first HTC smartwatch might be called One Wear - but that is just a rumor at the moment.
