As expected, Apple Watch has received an upgrade at the Time Flies event the Cupertino company hosted tonight. The new Apple Watch Series 6 models come with support to measure blood oxygen saturation levels, a feature that can help users stay abreast of cardiopulmonary complications, sleep apnea, etc. Another new thing is the new colour options the watch will come in: blue aluminium, graphite, gold, and Product(RED) hues. The smartwatch will, obviously, come with watchOS 7 out of the box. Apple has also launched a new service called Fitness+ for users of its Watch, TV, etc.
