Google is gearing up for the launch of the rival Apple Watch by giving Android Wear a major overhaul and highlighting some of its benefits.
The Apple Watch is now available to pre-order, and Google is keen to remind potential smartwatch buyers that there are Android alternatives.
Google appears to be making the most of the differences between the Android-based options and the incoming Apple version.
Several of the Android Wear software features have been updated. The firm pointed out that Android devices are always on and, unlike the Apple Watch, do not need a tap to be 'woken up'.
They also have a decent battery life, according to Google, and can use WiFi to serve data to a watch even when it is far away from its mobile phone partner.
"When you buy a watch you want it to, well, tell the time. So most Android Wear watches include an always-on screen. No tapping, twisting or shaking required to see what time it is," said Google in its Android Wear update advisory information.
"Now we're expanding this option to apps, so they can stay visible as long as you need them, instead of disappearing when you drop your arm."
The Apple Watch is reportedly greedy in terms of battery life, and the Google updates mean that the Android screen displays in battery-draining colour only when it is being viewed, the firm said.
Seven Android Wear watches will get these updates, the first being the LG Urbane. Google promises that the devices will be better connected, easier to use and more satisfying.
"Android Wear offers a range of watches and apps that are fashionable as well as functional," the firm said.
"Over the past few months we've added lots of ways to express your style, from custom watch faces to a rainbow of bands. Today we're making Android Wear more helpful as well, getting you what you need right on your wrist."
Android Wear users will also get more use of emoji icons and will be able to draw them directly onto the watch screen. Google said that the software will recognise what the artist is trying to draw, and return the appropriate icon.
