Google has announced the first smartwatches powered by its Android Wear operating system are now available for pre-order.
The LG G Watch and Samsung Gear Live - both featuring rectangular screens - mark an attempt to standardise the way Android wearable devices function.
Google said that Motorola's circular Moto 360 would not be released until "later this summer".
Analysts say the move to a unified approach could drive sales.
