Always used an Apple Watch in the past but I want to switch to the classic round watch style. I’ve narrowed it down to the Venue 4/3. I need the basics like notifications, answering calls, and sleep tracking. I also want heart rate, ECG and Blood O2 which I’ve read this watch does. Can the most recent readings of those show in complications ? I ask because I’ve lost those on my Apple Watch and I depend on them. Apple Watch complications for these only take you to the individual app now without showing the readings in the complication. Any iPhone users here that use these watches care to chime in ? Thank you !
