Patek-Philippe, Rolex, Jaeger-Lecoultre (JLC), Panerai tend to hold value better than brands like Omega, Breitling,Tag, Cartier, etc. In particular the Rolex sports stainless steel watches like the submariner have good resale values .But generally unless you have spent tens of thousands or unearthed a rare vintage watch you are not going to see a great return - they are not a good investment.
