Afraid not Giuliano. For one, the pushers and crown should at least be of titanium, which is mentioned nowhere. Further, what kind of ceramic? What kind of Luminious material is used on the hands? The movement CAL89361 is clearly stated indeed (which is great!) but I mentioned it to show that I cannot rely on what the folks in the store tell me.
It is all over the internet (3rd party sites) that the caseback is also made of titanium. Perhaps they mix up the Big Pilot with the Chronograph, as this site clearly mentions that the Big Pilot has a titanium caseback.
Anyway I think it's very remarkable that the information is so limited. I had a chance to flip through the manual (which is also on this site) but again nowhere are the materials used mentioned. Only the generic table stating the scratch resistance/breaking/weight for every single material (also note the different ceramics).
thanks,
Dan
