For what it's worth, I have a Garmin 645 smartwatch, which uses a transflective display; the user experience is about the same as e-ink. I love it. The "white" is kinda silver-grey, but it's perfectly functional, and I get a week's battery life. As a former Pebble owner, I think the trend toward smartwatches with OLED displays and short battery life is a terrible one.
