We still don't know an awful lot about the LG G Watch, but it seems LG is already looking ahead to what's next.
A patent filing suggests that another wearable, named the W Watch, is on its way and this one could be more focused on fitness.
There's an explicit reference to heartbeat measurement, as well as "receiving, processing, transmitting and displaying the information of exercise/body fat/BMI."
W is for wearable
It's unclear whether this is will be a successor to the as-yet-unreleased G watch or a separate device to exist alongside it.
But if the G Watch misses these extra health-based functions, it's possible that LG will offer two versions of its wearable: one for those who want a life assistant (Google Now) and one for those who want a personal trainer.
