In general, a redial hugely drives down the value of a watch. There are some tastefully done redials out there, but you'll find a lot of members on here generally gravitate away from redials in general. I find original dials much more attractive and usually of much higher quality than most redials.
Of the watches you're looking at, finding non-refinished examples isn't too difficult and just takes a little bit of patience. It's a bit of a minefield out there, so definitely post here first before making the leap and you'll get a lot of input on originality. You'll save yourself a lot of time and money by doing so, and hopefully end up with a great looking watch!
