Besides any legal considerations, what annoyed me the most was the lack of any kind words, friendliness or appreciation. You may have different opinions on a watch, you may value it different ( profit driven vs. rational approach, easy to tell what belongs to which party in this case.) but WoK obviously using 101 as a resource for whatever should have a different attitude.
They get exposure and publicity among people who are willing to spend fortunes, which is great for their business, hence they should cope with their own shortcomings in curating first...before they threaten to sue someone because they fail to do their due dilligence ( a romantic word for that would be "honesty" ).
I will rather continue to overpay for something I want and that's worth it, to private collectors, no bad taste in my mouth, no feeling of "well, almost what they promised me..".
