First thing we note: the cool rotating bezel makes a triumphant return. Compulsive fidgeters, rejoice!

Encircling the rear side, we find a constellation of holes for the mic, alti-barometric sensor, and speaker, as well as a brand new layout for the heart rate sensors and ECG functionality.

Haven’t we seen this ECG-layout before? It sure looks a lot like the Apple Watch Series 4.

This should also mean that one of the buttons has a sneaky upgrade to allow for pulse reading, so keep your eyes peeled!
