After reading your comments to my question, I went and research (in part) on the companies you mentioned.
I has been about 4 years that I am looking at a good watch. I tried a lot of them (Omega, Rolex, JLC, Audemar, Patek) and of course, price is a big factor.
I already own a very simple Tag Heuer Link Calibre S (was my first "good" watch), depending you compare it to what of course, you can argue that it was not the best choice but I could only afford that in that time. It will be 3 years and the watch is still perfect.
So, this time I am looking at a dressier watch (to wear with a suit or "officewear"). I have learned a lot in the last 3 years and today, I want a watch that is closely related to "horlogerie" more than "fashion and style".
JLC "speaks" to me a lot. I will investigate the cost to maintain and repair and the value of it if I sell it later in my life (as you told me, very smart of course).
