To install using Linux and ota-dfu:
* Look up the MAC address for your watch (try: `sudo hcitool lescan`).
* Use ota-dfu to upload `micropython.zip` to the device. For example:
`tools/ota-dfu/dfu.py -z micropython.zip -a A0:B1:C2:D3:E3:F5 --legacy`
At the end of this process your watch will show the time (03:00) together
with a date and battery meter. When the watch goes into power saving mode
you can use the side button to wake it again.
