Although LG hasn't really tried to keep the G Watch a secret, they're not exactly going out of their way to tell us all about it either but that may soon be coming to an end. Hitting the FCC recently is what is reported to be one variation of the G Watch otherwise known as the LG-W100. According to the documents, it's listed as smart watch with Bluetooth and Bluetooth LE but lacks mention of any 3G or 4G connectivity.
That lends credit to the idea that this version, the LG-W100, would be more of a traditional watch while the other version discovered, LG-W015L, would be the full-blown smart watch version capable of making calls. That's pretty much where the information ends for now however as very few other details can be gleaned from the filing. We'll just have to wait and see what comes next for LG's first Android Wear device.
