Google unveiled the first smartwatches to use Android Wear: the LG G and Samsung Gear Live.
Android Wear is a version of the mobile OS developed for smartwatches, using the Google Now personal assistant to push relevant information from your smartphone to your wrist.
Google revealed a few more details about Android Wear at its annual developers' conference I/O. There will be two UIs, one for square watches and one for round faces, with "cards" of information you can flip through.
When you get a notification on your phone, the watch will show it - even vibrating on your wrist to get your attention. You can send messages or make notes via voice, and set reminders to trigger when you get to a location such as your own home.
Google is only now releasing an SDK for developers, but two watches will be available to buy imminently.
The LG G features a 1.65in, 280 x 280 IPS display and runs a surprisingly powerful 1.2GHz Snapdragon 400 processor on 512MB of RAM. It has 4GB of built-in storage and a 400mAh battery.
The LG G watch will cost £159 (approximately $287), and is currently taking a week to ship.
The Samsung Gear Live, meanwhile, features a 1.63in Super AMOLED display with a resolution of 320 x 320, and runs a 1.2GHz chip and 512MB of RAM. It also has 4GB of built-in storage.
The Samsung Gear Live Watch costs £169 (approximately $305) and at the time of writing was scheduled to ship on 7 July.
The previously announced Moto 360 was missing in action, but Google said it would arrive later this summer.
