1- You cannot have only one watch. Need at least two for dress watches to alternate, plus a beater, in addition to the grail
2- Once you have acquired the "grail", most likely you will start searching for the next "grail" on your list. We are never satisfied with just "one grail"
3- No one is ever satisfied with only one watch. Just impossible JMHO and obsevation.
