Apple's online store down ahead of iPhone XS, iPhone XR and Apple Watch Series 4 preorders

Apple introduced its first major Apple Watch redesign with Apple Watch Series 4, squeezing larger OLED displays, greatly enhanced heart rate monitoring capabilities, a new S4 SoC and revamped internal sensors into a slimmer chassis. 

Starting with the screens, Apple says the nearly edge-to-edge displays are 30 percent larger than previous Apple Watch models. Despite the larger size, Apple managed to keep battery life consistent with last year's models by integrating LTPO technology. Taking advantage of the extra real estate are first-party apps and watch faces with redesigned user interfaces. 

Apple Watch's heart rate sensor has been completely reworked to accommodate a new electrical sensor capable of taking ECGs, useful for identifying potentially life-threatening issues like atrial fibrillation. Electrodes flanking the optical heart rate sensor pair with a redesigned Digital Crown that receives electrical signals sent across a user's body, from wrist to fingertip. Apple was able to secure clearance from the FDA for both the ECG and aFib detection.

In addition to playing an integral role in ECG readings, the new Digital Crown now supports haptic feedback. Apple Watch's speakers have been redesigned to be 50-percent louder, while its microphone has been relocated to boost audio quality. 

Internal sensors have also been upgraded, affording higher degrees of accuracy. Apple takes advantage of the new capabilities by integrating unique features like fall detection.

Instead of different models of the Apple Watch using different composite materials for the backs depending on model, all models of the Series 4 will come with ceramic backs, a material that affords better cellular transmission and allows for the advanced cardiac monitoring that the device now provides.

Apple Watch Series 4 will be available in 40mm and 44mm sizes. The usual silver, gold, and Space Gray aluminum hues are back, while stainless steel versions will be sold in silver, Space Black and a new gold color. Nike+ models with special watch faces and bands are also available.

Prices start at $399 for 40mm aluminum versions with GPS, while 44mm models go for $429. Aluminum models with cellular connectivity sell for $499 for 40mm and $529 for 44mm. All stainless steel models include GPS+Cellular capabilities and start at $699 for 40mm sizes and move up to $749 for 44mm.
