Homebrew binary watch?

Anyone created a home made version of the binary watches you can get now
(like this one http://www.thinkgeek.com/gadgets/watches/6a17)? They look so
cool!

I was thinking of using a PIC and watch (32,768) xtal possibly with a
seperate I2C RTC device. Most of the devices that would fit in a watch case
are SMT which I have no experience of in homebrew. Is there anything like
the equivelant of breadboard for SMT devices?!

Any thoughts appriciated,
James

breadboard for SMT devices?

The clearances are so tiny that it's not a good idea.

You can always mock it up on a breadboard, using through-hole
components. Then, scale it down on the real deal. Nothing beats a
circuit sim, though.

Wouldn't have to worry then about SMT I suppose :)
