Do you state that it has its own display RAM or doesn't it?

240x240 is ~56.25 kB at 8 bpp. the screen is RGB 65K colors, that is, 16 bpp; so the framebuffer size should be twice larger. I assume that the display controller has its own memory. True, you would need another 112,5 kB for double-buffering, but maybe you can do without it.

Color displays are great, but they should have had an option for a (color or black and white) e-paper display. More efficient for these purposes imo.

I would pay so much for a hackable watch like this with a 3 or 4 color epaper display, I'd almost pay as much as an apple watch if it was high quality hardware and had a great open API and toolchain.

Go on ebay and purchase a Pebble Time. Color epaper display, fully hackable even after being discontinued thanks to the dev community who continues to update it with "Rebble" the open source version of the OS it ran on.

ePaper is just their name for a transflexive LCD display. It's not eInk type technology

Thanks!

I'd pay more than for mass produced consumer gear, from any manufacturer.
