I think that rlx prices are in line to all high quality swiss watches.
This is the link of a seller of used and vintage watches in my town

see it, the price of the perfect GEN 5513 vintage is similar to others watches.
You have reason about a restrict number of particular models, that have high high prices, as 6263 and the daytona V722 family, as Comex, as DRSD.
But in Italy a standard vintage sub vetroplexy has a price similar to an used modern submariner
A entry level Patek Vacheron or AP has a price very hig respect to this sub vintage
I think that a Patek Worldtime has a superior quality , but a simple Calatrava is not a super iper lunar watch, but if a sub vintage costs 1, a Calatrava costs 3 !!!!!
Really, all the swiss watches hig level, not only rlx, are very overpriced !
But if you love it, you buy it. It is not another solution.
