The only job of the USB port is charging the internal LiPo battery. The
data lines are not even connected to the little PIC computer. I don't do
apps.
I suppose a clever person could work out who to do an entire smart watch
interface with two Nixie tubes...

So, will the USB port also be used to charge internal Li-ion batteries ?
Gotta drink more beer, to get those beer cans !

Folks,
I have been working on the fiddly bits of this watch design. The
waterproof USB connector is installed, and the case now has an o-ring
seal. I also updated the computer to a 40 pin unit (5x5mm QFN) to
provide for battery voltage monitoring. The window is larger, to afford
a better view of the tubes.
The geometry changed a bit, but the overall dimensions are the same:
48mm wide, 51mm tall, 16mm thick.

I think the project has momentum enough to get another batch of
prototypes made. Should be interesting!
