Online retailer Best Buy briefly listed the most-awaited round-faced Moto 360 smartwatch on its website for $250 along with detailed specifications.

Best Buy, one of the largest online retailers, offered a quick peek at the much-talked about Moto 360 smartwatch. The retailer gave away most detailed specifications and the pricing of the Moto 360 on Sunday's leak. The product listing was removed soon after it went viral but Droid Life captured the screenshot of the webpage showing Moto 360 on Best Buy retail site. The official unveiling of the smartwatch is expected to take place at an event in Chicago on September 4.

If the Best Buy listing is to be believed, the Moto 360 will sport a 1.5-inch backlit LCD touch screen round-face display with a 320x290 pixel resolution and 205ppi, protected within Corning Gorilla Glass 3. It will be powered by Google's Android Wear OS, designed exclusively for wearables, and a processor by Texas Instruments backed by 512MB RAM.

The Moto 360 will feature sensors to track wearer's fitness such as an optical heart rate monitor and pedometer. Like other Android-based smartwatches in the market, the voice-activated smartwatch by Motorola will be compatible with Android 4.3 Jelly Bean and above using built-in Bluetooth 4.0 LE.

Moto 360 attracted several wearable enthusiasts as it made rounds at the Google I/O event earlier this year. The watch will feature a stainless steel casing, leather band and a metal buckle. The lithium ion battery with a LED indicator is encased inside the smartwatch, held firmly by a plastic back cover. Analysts have predicted strong sales of the premium-looking smartwatch, which is nothing like Samsung Gear series or the LG G Watch.

When HNGN interviewed Moto 360 Design Face-Off contest winner David Pascual, he had all great things to say about the smartwatch.

Other leaked specs suggest the Moto 360 can withstand 3.3 meters of water for 30 minutes, making it useful for daily wear.

Samsung currently dominates the smartwatch sales in the US and Pebble smartwatch maker places second rank. Apple is also expected to launch its much-rumored iWatch sometime later this year or early next year.  So, Motorola will face some tough  competition.
