Pebble did not use e-ink screens, it used a reflective memory in pixel LCD (I believe made by Sharp), refresh rates were never a problem using that technology, because it's just a LCD that has some tweaks for lower standby power usage. More on it: https://www.sharpsde.com/technologies-for/memory-in-pixels/m... It still requires a very small amount of power to keep the screen functioning.

E-Ink uses a completely different technology that does not require energy to continue displaying an image on the screen. Only requires it to change it. Operates by moving charged polymers to make them go to the surface or fall away, similar to etch-a-sketch (edit: I was thinking magna doodle) toy, but charge/not magnetism.
