I am new and looking around having bought several reps one of which is a Panerai. Now I want to have one on a metal and one on leather. I have the steel bracelet half shiny and half brushed next I want to buy a titanium one and put it on leather. Anyway the numbering system of these (111h, 164,024, 253) are driving me a little crazy. Without wasting anyone's time is there a simple chart that has size, movement, material, color etc. on it? Thanks in advance.
