I got distracted today... There are these 'smart' watches on eBay right now called iDO / DO 003. If you look on eBay for 'fitness watch' and then find ones that look similar, you'll see you can get them for under £10 in the UK, including postage.
They're wireless, with the same nRF51822 chip in as the micro:bit (which I now have Espruino running on) - which got me thinking....
