We all have in mind brands that provide different levels of finishing in there colection (whether for the material or for the engraving, chamfering, hedging quality etc ). JLC is a good example.
I think that these differences must be very clearly identified by the client.
Thus, if you have a same watch sold in different finishing gradings it will pull down the best quality watch's image, and hence the price the customer is willing to pay for it.
There is, to me, one exception: the material (gold, steel, Titanium, Pt). But the mouvement and quality of surfaces finishing must be the same, for a same watch.
Do you have something in mind ? ^^
