Dear fellow purists...I need your expertise.
I am thinking about buying a Blancpain FF GMT on the secondary market and am wondering what are my options. I have seen a couple for sale but I am sure one type was part of a Trilogy selection (what does this mean ? ) and one of them didn't state anything about Trilogy, yet both watches looked identical. Are there two different models?, if so whats the difference between them. I have attached a pic so you can see which watch I am talking about
