Any ideas what the screen refresh rate is going to be at this point? All the screenshots don't have time that includes seconds, and having a watch face that can update at least every second would be a requirement for me.

(I know e-ink displays can have fast refresh rates, like the 60Hz / fps Daylight computer - but that may not be cost effective / battery efficient here?)

It's a sharp memory lcd (not eink, sometimes called epaper): https://sharpdevices.com/memory-lcd/#1615979030123-5695809f-...

The Daylight computer DC-1 isn't e-ink it's a reflective LCD by the way. Different screen technology.

TIL! Thanks for the link - all the demos / videos had me convinced this was just e-ink technology!

What is the impact on battery life to have the screen update every second, versus every minute? Will it be possible to have the HR display, on faces that include it, rate-limited to achieve better battery life?

One of the nice things about Amazfit watches was that I could dial down the HR polling and get better battery life that way.

I think it's a little bit more. I don't know if I've ever measured it. You can definitely see it in battery life though. Using a watch face that only updates every minute will give you longer, better life.
