I only have experience with selling 2 G-Shock Squares and I shaved off like 30% of what I paid back in the days. To be fair, I wore it more often than once but also with no sign of wear and tear. I sat on it between 2 weeks and 2 months after put it up on sale on something similar to eBay. I hope this helps. Which models are you selling? Rather popular ones or not?
That's the problem with discounts in my opinion. They are shady and not equally accessible to everyone. But of course I see the argument. Some people are too obsessed with value. Interestingly the many people who are pushed out of the market by price hikes are sacrificed as potential customers happily over the fear of pissing of old customers who might have overspend.
