Hi there!
I'm a beginner collector; I buy and sell used watches.
Sometimes I see excellent watches (Grand Seiko, Omega, Breitling) attractively priced, but without a box or papers.
Most of the watches I buy will be sold ('catch and release').

Please share your opinion:
1. Would you consider buying a No Box No Papers (NOBNOP) watch?
2. How much of a discount would a used NOBNOP warrants compared to a used box-and-papers watch?
