@maple @Nine oh, and if you find yourself in need of more water resistance then you can fill the thing with mineral oil
I've seen someone do that and then expose it to 100ATM of water pressure and it survived which is hella neat
And if you muck the process up and end up with air bubbles in it the watch now also functions as a spirit level
@maple @Nine oh also, if you want to change the backlight colour then it's a really simple job, just needs an 0805 LED swapped out
And if you want a negative display you just need a bit of polarised film
