The much rumoured Apple Watch Series 7 design changes don't appear to be all too drastic, but for the supply chains manufacturing them, it appears to be a different story. As per reports by Nikkei Asia and Bloomberg’s Mark Gurman, Apple is apparently halting production on the upcoming Series 7 due to increased difficulties during assembly leading to an unacceptable rate of failed quality control checks. 

The sources speaking to one of the publications allege that due to the higher "complexity of design", Apple contracted assemblers "found issues when putting together electronics modules, components and displays". 

Originally, all signs pointed to Apple getting prepared to release the new model in September, however, while these new reports clarify a delay is in order, it's unknown for how long that might be.  

Ultimately, while the new flat edge chassis is most definitely contributing to this, Nikkei Asia claims that an all-new blood pressure monitoring system making its debut in the Series 7 is creating difficulties in the water-proofing aspect of the watch’s design as well. 

Bloomberg's highly reliable Mark Gurman later confirmed in a statement,
