In that case, I'd recommend the 12F series.  ;)

But yes - I would go with the 12F683, since it's the only one with an 
LFINTOSC low-power internal clock mode.  It's spec'ed at 11 uA typical 
in that mode at 2V.

If you need to use an external crystal for some reason, then you could 
also use the 12F629 in its LP mode (32 kHz external clock) and you might 
get lower power usage (spec'ed at 9 uA @ 2V).

You could probably use a 10F too, but I haven't used them personally.
