A4C via eBay offers the refurbished Samsung Gear S2 Classic Smartwatch for T-Mobile in Black for $125.99 with free shipping. That's $4 under our December refurb mention and the lowest price we've seen. (It's also the best deal for a refurb today by $4, although most retailers charge at least $160.) It features a 1GHz dual-core processor, 1.2" 360x360 Super AMOLED touchscreen, 512GB RAM, 4GB internal storage, WiFi, Bluetooth 4.1, stainless steel case, and leather strap.
