Nice! So you still have to open the watch to get Espruino on it - but once that is done you can DFU back?
Is there a chance that some of these watches either use the bootoader in debug mode (so it doesn't check the key) or use the OEM Nordic private key?
It looks like I may have somebody who is interested in ordering a bunch of Espruino watches so I'm looking into this a bit more - but it'd likely be a watch rather than a band as you get better displays and a bigger battery. If there was a way to get these flashed without having to do a custom order it'd be awesome.
