Motorola has already released the Moto 360 in three outlets. It was a widely-anticipated smart watch after Google released Android Wear in 2013.

Experts believe the Moto 360 is still the most anticipated Motorola smartwatch until now. Unfortunately, the company announced it had run out of stock only three hours after the phone's release.

People eager to buy can sign up on the Motorola website to find out when stocks are back. Best Buy listed the Moto 360 as sold out after it said all of its stores would have the smartwatch until Sept. 14.

The Motorola website and Google Play Store listed it as sold out, as well. Motorola posted a tweet saying the Moto 360 was sold out and that availability may be limited for a while.

The shortage is due to Moto 360's appealing look and its distinct features, including its 1.56-inch display, water resistant body and wireless charging.

The smartwatch comes with a circular body with LED screen, offering 320 x 290 pixels resolution. It's covered by Gorilla Glass 3.

The Moto 360 also has health features such as a pedometer and heart rate monitor. It can be immersed in 3.3 feet of water for 30 minutes without damage. You can also connect it to your smartphone through Bluetooth, allowing you to view email, calls and SMS notifications.

The Moto 360 has a couple of competitors, including the recently launched Apple iWatch; the Samsung Gear S, which has a 3G SIM for accessing the web and making calls, the LG G Watch R, which also has a round display, the Asus Zenwatch and the Sony SmartWatch 3.
