You've focused on two superb models that reply perfectly to your criteria (but, the 177's dial is black).
* Pros for the 177: cheaper to buy and service, initial depreciation taken by someone else, no "8 DAYS" on dial.
* Cons for the 177: necessarily used (unless you somehow score an NOS), less of a power reserve than the 564, black dial (if you want brown).
* Pros for the 564: 8-day power reserve, can buy it new, brown dial (if that's what you're looking for).
* Cons for the 564: will be more expensive, "8 DAYS" on the dial.
Good luck with the choice!
