Final passage as follows:

"So, what have we learned here? The price increase of luxury timepieces unquestionably is a complex topic and one that we are definitely going to further elaborate on in the future. As a first step, we hope to have shed light on some of the previously unseen aspects of how prices and also personal income levels have changed over half a century. We have seen some of the steps in the long and rather intangible process of how Rolex watches have become a luxury item from a tool, initially tailored for professional use."

So let's read the article and see what we think of it.
