I bought the Panerai Luminor Titanium model PAM00352.
Since it is an old model, it is thicker than the current model, but it is overwhelmingly lighter than the 328 and 299 stainless steel bracelet models I have. It is lighter than the thin bracelet 1058, and it seems to be comfortable to use thanks to the material of titanium.
I've been buying Panerai watches at a pace of one every year since 2007, but I felt that recent models are becoming more luxurious and less rugged than they used to be. That's fine, but somehow I wanted an old model and bought the 352.
I am very satisfied with the model that gives me a strong sense of Panerai.
