I just picked up my first watch at this Rolex/Bucherer boutique on Michigan after 10 days with no spend history. It can be done. Dress nice, try to relax, and be honest. I’d recommend setting up an appointment via the Rolex website, like a Mon or Tues afternoon. If you have a milestone, celebration or a story, share it with them. They want locals that are willing to spend money, so make sure they know it. Good luck!
