The Apple Watch Series 6 packs the latest features and looks perfect in Navy Blue, all for $324.98 shipped, this weekend only, originally $399. Unlike its predecessors, this model can measure your blood oxygen saturation, or SpO2, which represents the percentage of oxygen being carried by red blood cells from the lungs to the rest of the body. It does so by using four clusters of green, red, and infrared LEDs, along with the four photodiodes on the back crystal of Apple Watch, to measure light reflected back from blood. Product page.

Apple Watch Series 6 (GPS, 40mm) - Blue Aluminum Case with Deep Navy Sport Band
  • GPS model lets you take calls and reply to texts from your wrist
  • Measure your blood oxygen with an all-new sensor and app
  • Check your heart rhythm with the ECG app
  • The Always-On Retina display is 2.5x brighter outdoors when your wrist is down
  • S6 SiP is up to 20% faster than Series 5

The Apple Watch then utilizes an advanced custom algorithm built into the Blood Oxygen app, which is designed to measure blood oxygen between 70 percent and 100 percent. Real-time measurements can be taken while the user is still, while periodic background measurements happen when inactive, like during sleep. It’s also much snappier, thanks to Apple’s A13 Bionic chip. The upgraded S6 SiP runs up to 20 percent faster, which means apps also launch 20 percent faster.

Apple Watch Series 6 completely redefines what a watch can do. With powerful new features, including a Blood Oxygen sensor and app, Apple Watch becomes even more indispensable by providing further insight into overall well-being,” said Jeff Williams, Apple’s chief operating officer.
