The LG Watch Urbane 2nd Edition, the first Android Wear smartwatch to feature cellular connectivity, will begin rolling out worldwide starting this month in the United States and Korea with markets in Europe and Asia to followin the months ahead. Compatible with both Android and iOS smartphones, the LG Watch Urbane 2nd Edition allows users to answer calls and check messages without the assistance of a tethered smartphone.

The LG Watch Urbane 2nd Edition features a classic timepiece design consisting of a stainless steel body and a full-circle 348ppi P-OLED display. The three buttons on the right side provide quick access to shortcut settings, LG Health and apps. Moreover, its high-capacity 570mAH battery and Power Saving Mode enables the smartwatch to last throughout the day with power to spare.

AT&T is already selling the device online with in-store sales scheduled for Friday. The smartwatch will also be available for preorder online through Verizon from Thursday.

The watch AT&T is selling runs on a Qualcomm Snapdragon 400 chipset and has internal memory storage of up to 4GB and 768MB RAM.

Samsung Electronics' Gear S smartwatch offers 3G cellular connectivity for calls and texting when away from the phone, besides Bluetooth and Wi-Fi. But the smartwatch runs on a Tizen-based wearable platform and not Google's Android Wear.
