On the decidedly bright side of things, you have no reason to worry about functionality here (at least if you trust Woot’s testing process) and the battery of your Apple Watch Series 4 refurb should also work at “minimum 85% capacity”, which is really all you can hope for when buying such an old product.
Naturally, the Series 4 is overall faster than the Series 3, not to mention larger, especially in the 44mm variation sold at $129.99 today (and today only) with a space gray case and black sport band. This bad boy comes with a beautiful LTPO OLED Retina display capable of a resolution of 368 x 448 pixels, and perhaps most notably, it’s the first smartwatch of its kind to detect falls and take electrocardiogram (ECG) readings to continuously and carefully monitor your health.
With the help of watchOS 9, the Apple Watch Series 4 will soon enough be able to keep an even closer eye on its wearer’s atrial fibrillation history and sleep quality, and if you hurry, you can get all that in exchange for just 130 bucks.
