I'm more of a digital watch nerd.

In my school days I had one of these:

Calculator, address book etc..

And one of these:

IR remote control. My dad's car had central locking operated by IR, which I programmed into it - so I felt like James Bond unlocking the car with my watch

One day I wore one on each wrist, which I have never lived down to this day

I usually wear a Pebble now.
