The Apple Watch Series 8 isn’t a huge upgrade over the Series 7, but it’s still the best smartwatch out there. And today it’s cheaper than ever: Amazon sells the 41mm for $329.and the 45mm Apple Watch Series 8 for $359 at midnight, a $70 savings and the best price we’ve ever seen.

The Apple Watch Series shares the same design and screen dimensions as the Series 7, but features a new temperature sensor for fertility tracking and built-in glitch detection. It features a 41mm or 45mm display with ECG and blood oxygen sensors, 18-hour battery life, IP6X dust resistance and WR50 water resistance, plus a great always-on display.

In our review of the Apple Watch Series 8, we called it “a smartwatch to be surpassed.” And at this price, it’s simply impossible to beat.
