It’s not a matter : of aren’t we nitpicking here? Or “diminishing the over value. ..”
handmade guilloche has a very specific and well understood meaning. If you say it, you are saying in effect, …by a rose engine.
It’s not about diminishing the overall value. But diminishing the overall credibility of the firm marketing the product. And yes, diminishing the overall cost of a good sold does diminish its overall value of the goods being sold.
It may not decrease the overall desirability or scarcity which could make up for that reduction. But something made more cheaply is cheaper. Whether it is a store of value is determined by the subsequent highest bidder, not by the owner.
There is a concept called truth in advertising and like another poster here ( who makes the central point ) the customer has the right to be informed and the right to choose based on the truth.
I have a neo vintage chronoswiss Delphis. The dial is stamped. I purchased it at a diminished value years after it was produced. I’m very happy with it at the price I paid, knowing exactly what I purchased. Besides being enjoyable to wear, I believe it will be a store of value at the price I paid, but I would not have bought it at the price originally offered.
But I digress.
The point here is that we cannot redefine an agreed upon term to suit our sales plan and increase our sales margins unless the market redefines the term. that’s ignorant at best and deceptive at worst.
