When Apple launched the Watch Series 7 in October 2021, many expected the smartwatch to have a host of new health-tech features for the user to enjoy. Watch Series 5 introduced an electrocardiogram (ECG) while the Watch Series 6 added a blood-oxygen monitor or pulse oximeter, the latter a fitting feature in the context of the ongoing COVID-19 pandemic.
But when Apple revealed the hook of the Series 7 would merely be a larger and much more durable display – along with an expected IP6X certification for resistance to dust and a WR50 water resistance rating – many were baffled.
