You can get a really nice Omega/Breitling/Tag for much less than 9k, no? Rolex just seems to be the luxury watch among high end watches.
Rolexes also keep their value incredibly well. I bought a nice Tag many years ago (I knew nothing about watches) and it’s now worth about $1000 on the used market at best. Had I bought a similar priced Rolex instead, it would have kept its value, if not even appreciated.
Watch market above that starts getting weird. You have some special models, technically equivalent w/ cosmetic bling hitting $80-100k
