@jextxadore The Amphibia has a stainless steel case and an acrylic crystal that's 3mm thick, but the nice thing about acrylic is you can polish out the scratches with Brasso or even toothpaste. In any event, I'll never be in a position to afford a Rolex or a Patek Philippe, so I'm happy to play around with the proletarian Russian stuff. :-)
