Breed via Amazon offers the refurbished Samsung Gear S2 Android Smartwatch, model no. SM-R720, in Dark Gray for $104.95 with free shipping. That's $120 under our July mention for a new one, and $5 under the lowest total price we could find for a refurb today. It's compatible with devices running Android 4.4 or later and features a 1.2" 360x360 AMOLED touchscreen with rotating bezel controls, 1GHz dual-core processor, 512MB RAM, 4GB internal memory, S-Health app for fitness tracking, Bluetooth 4.1, 802.11n wireless, stainless steel case, elastomer strap, built-in wireless charging, and IP68 dust- and water-resistance.
A 90-day warranty applies, but it's not clear who backs it.
