I've owned a couple of wear os watches before switching to a galaxy watch active 2 and both of my wear os watches supported a second hand on the AOD. I'm missing the feature more and more each day, it baffles me that Samsung took this feature away from its customers.
On my wear os watches I got better battery life with the second hand on the AOD and tilt to wake gestures turned off as I rarely needed to actually wake my screen. Surely Samsung watches could be used the same way and depending on use case see minimal battery drain compared to constantly relying on the use of gestures to see a second hand? I get that there's a focus on having a simple AOD but at least give us the choice Samsung!
