I started to collect watches. I bought a Patek Calatrava 3800/200 from an authroized dealer 2 yrs ago. I have a Rolex steel and gold for many years cause when I was younger I only knew Rolex. Recently I bought from an official dealer a JL Reverso Classique Steel and a Master Moon in steel. I find out JL are very nice watch. I have an eye on a Rose Gold Master Thin. The Manager of the dealer said I spent a lot in 2 weeks buying the two Jl. He said for a much lesser price, he can order a JL Master Thin in Steel for me the next few months. He said Caliber is the most important thing and buying a Master Thin in Steel is considered a wise decision. Can anyone give me an opinion on that?
