With its new iPhones delayed at least a month, Apple instead just launched two of the other products it would normally announce at its September event: New Apple Watch and iPad models.

First up was Apple Watch, which will soon be powered by watchOS 7 and its new features like sleep tracking, automatic hand-wash detection, and improved VO2 max testing.

Apple announced the new Apple Watch Series 6, which looks physically identical to the previous models but offers 20 percent better performance and comes in some new and updated colors—new blue aluminum and Project [RED], plus updated classic gold and graphite.

There’s also one major new feature, a Blood Oxygen sensor. This can be used manually at any time—the test takes about 15 seconds—and it will also perform periodic background readings, such as when you sleep. And in the future, you’ll get notifications if your blood O2 level falls too far.

The Apple Watch Series 6 display is much brighter than its predecessor, Apple says, and offers an always-on altimeter so that it can factor altitude into its measurements. Finally, the firm announced a few new types of Apple Watch bands, two of which are stretchable single-piece units that don’t require a clasp.

Apple Watch Series 6 will start at $399, but Apple also announced a lower-cost version of Apple Watch called Apple Watch SE. It uses last year’s designs and even older internals but starts at just $279. Both devices are ready for order now and will ship Friday.

Finally, Apple also announced its first online service aimed at Apple Watch owners. Dubbed Apple Fitness+, it provides a wide variety of Apple Watch-compatible workouts that can be accessed on iPhone, iPad, or Apple TV, and the firm says it will add more every week; it launches with workouts for yoga, cycling, dance, treadmill, strength, core, fit, rowing, and mindful cooldown. The cost? $9.99 per month, or $79.99 for a year.  It launches later in 2020.
