Well, it works, but it hasn't had enough work put into it to be super useful. There's a branch in GitHub where I built the OLED driver into C code which should free up some more space for JS, but it's untested.
However I don't think the watch you posted is the right one - if you look at the first few posts you'll see the watch I had has the display smaller and running in the opposite direction.
If it's an nRF51-based watch then I'm sure you could get it going, but you'd have to follow the pretty arduous route I took of trying to trace out exactly which pin goes where for the display.
What'd be amazing i if someone could find an nRF52-based watch. I'm not sure if they exist, but if they do they'd have bags more RAM and flash available for useful/fun stuff.
