Re: No money in it
Not really the same point, but you can certainly consider ROI a factor in haute horologie. General rule of thumb is that if a watch costs less than $5k it will depreciate over time, whereas those costing more than $5k will appreciate. Hence ROI.
Rolex doesn't dabble in haute horlogerie, presumably because they sell strongly enough already. That "rule of thumb" is not something I've come across before. Only very few watches (and in the case of Rolex, only a handful of models) have historically appreciated in real value, regardless of list price.
ROI... As with cars, I can only say good luck to anyone who wants to invest in luxury watches!
