As tech companies continue to invent and create revolutionary devices, people will also keep on looking for more. In the wake of Google's Android Wear operating system for wearable smart devices, a number of devices have been announced. But which will be the best Android smartwatch? Check out our comparison of three front-runners below. Although not much is known of their specs as of yet, experts have made some educated guesses based on what features have been announced.

LG G Watch

The LG G Watch is voice-controlled and touch-controlled. The LG G Watch is square shaped and available in two colors, champagne gold and stealth black. Its strap can also be swapped out to customize its appearance. The display does not turn off, so it is likely to use OLED technology in order to avoid wearing out before the day is over. According to LG, the LG G Watch is sealed so it can withstand dust and water and it has a long battery life. It appears to be charged through gold contacts on the back. The LG G Watch will cost around $300, reports Load the Game.

Moto 360

This watch has a gorgeous design featuring a recognizable circular body. Moto 360's circular screen is also widely believed to be a battery-saving OLED display and speculated to be protected by a durable but expensive sapphire glass screen. The lone knob is located on the side of the watch face, making it available whether the watch is worn on your left or right arm. The UI can be flipped around to keep it visible from whichever hand the watch is worn on. Since the rumored OLED display would save battery life by turning off individual pixels when they are unneeded, it is expected to have good battery life. How that battery gets charged is still something of a mystery, due to the lack of a visible port for a charger wire, but it is likely that it makes use of Qi charging due to its distinctive backing reminiscent of this wireless charging technology already seen in some Nexus devices. Motorola has not released any other details about Moto 360, so it is still unclear if it is weather resistant or if it has a camera. Moto 360 is expected to cost about $299 when it is released this summer.

Samsung Galaxy Gear

Made of high quality stainless steel, the Gear has a square touch screen that features messaging, time, and music control and comes in different colors. It reacts to your voice or fingers through the optimized S voice, making spoken and typed commands fast. It has a SAMOLED 4.14 320x320 display, 800MHz CPU, 1.9 MP camera, 13.4mAh battery, and Bluetooth connectivity. The GALAXY Gear's complete specs are available on the Samsung website. Since it is several months old now, its price is unsurprisingly lower at about $200.
