1 Minute (and over ) WDT

how about a 555 timer?
i would however be stunned if you can't find a few intruction cycles & program space to for example
increment a counter on a TMR0 generated interrupt, even if you are using TMR0 for something else too
- it's not like you are in need of precision timing by the sound of it.
