Yeah, we know, it doesn't run Android, but the Gear S2 is still an awesome smartwatch. Its innovative rotating bezel is something no other touchscreen-equipped watch has (save for the S2 classic and the upcoming S3). Now, you can pick a manufacturer refurbished Verizon model up from an eBay seller with 97.5% feedback over nearly 120k ratings for a penny under a Benjamin.
Don't let the fact that this is a Verizon model turn you away. It may not work on other carriers as a standalone smartwatch, but as a regular one tethered to your phone, it still functions perfectly. It will work with any Android phone running 4.4 KitKat+ with 1.5GB+ of RAM. In addition, even if your smartphone isn't on Verizon, you can still grab a Verizon plan for the S2 and have calls forwarded to it without any issues.
Unfortunately, this is a US-only deal. It's still pretty sweet, considering Verizon will sell you a new one for $349—nearly $250 more than this price. If you're interested, you should hurry, as eBay says there's a "limited quantity available". Only the black color is available as of this article's publication. The watch will ship from Brooklyn, NY in a generic box with a charger.
