Chess Timer (sort of) Needed

I have a need to run 2 timers, alternately, counting up from zero in minutes. When one is running the other is stopped. Additionally, it would need a reset to zero function. I would assume a 556 clock chip would do this function with some external switching. Not real familiar with this circuit, need a little help finding a diagram.
