Just a point in question: Patek Philippe brand of watch, only goes up in value, exponentially, observed from all the research I've done, .. . . . so, if you can afford a second hand model in their range, . . it will not only be an investment, but will hold it's value too. (I wished I had bought one back in 2016/2017, as the model I was looking at, has increased in value between + £25k - £30k, . . . . . almost doubling in value!!?
