If you've been wanting to get your hands on a second generation Moto 360, now is the time. Google today removed the listing for the device from its online Store. In fact, Motorola confirmed at the beginning of December that it has no foreseeable plans to make a new model.
Luckily, there are still some third-party retailers that you can get the smartwatch from (Motorola doesn't sell it from its website either), such as Best Buy. The retailer has three models in stock, but they're all on clearance, so you'll want to hurry up. You can get the 46mm gold and black model for $322.99, the 42mm gold stainless steel model for $303.99, or a refurbished 46mm Sport for $154.99.
It's likely that the company is clearing out inventory in preparation for next month's Android Wear 2.0 release. There should be two new LG smartwatches that ship alongside the new OS as well; however, if you already have the second generation Moto 360, it is slated for an upgrade.
