I understand your attitude based on experience.
Here is a different kind of forum. It will be worth your time.
You don’t need any history to buy here, although sellers may be circumspect dealing with you until they know you.
The private sellers here sometimes ask more than dealers - but for special watches - something that you may appreciate with your car history.
Then there are flippers, private sellers with a hunters instinct, that need to sell to replenish their ammunition.
Watches sold here by collectors are often much better in that they are original, or presented with full disclosure.
For us private sellers, our reputation is worth more than the profit we might have to make as dealers.
As a general rule, with a few exceptions, the best watches are held, and sold, by private collectors
