....from memory.There are several models with the designation 1950 but it refers to the case type and not the print on the dial. More than breakable, I would define the composite material....fragile. It can flake under some different conditions. It could be particularly acid sweat, immersion is certain substances (can include alcohol). Many a Panerai gets immersed in beer as a christening of sort. Not with the 375 or 339 or other composite models. On the official Panerai website, there is a 1950 section that can be perused at your convenience Ciao
