Re: There is *something* somewhere ...
"Or you could ditch the daft, geeky feature list and go with something sort of retro / steampunk. Maybe purely mechanical, with little gears and a way you could see them?......(looks at own wrist)."
Or you could even put a glass window in both front and back so you can see the little gears from both sides - the glass could be protected with a couple of flip open covers, activated by pressing a little stem on the side of said device - hey, you could possibly even adapt the stem to be be a multipurpose case opening/power input/programming device. .......
