官方说法表壳使用的是德国潜水艇的钢。关于此钢：submarine steel
Special grade of steel developed by ThyssenKrupp for the outer shells of the very latest non-nuclear submarines, the 212 class, of the German navy.
Our U series diving watches are made entirely from this special grade of steel.
This material is 100% austenic steel; it is exceptionally strong and has superior non-magnetic properties. Its mechanical strength is more than 1.55 times that of the usual watch case steel AISI 316L.
A further advantage of using this steel in the manufacture of diving watches lies in its unique saltwater resistance. Normal case steel has to be rinsed in fresh water after contact with saltwater, as long-term exposure to saltwater can, in adverse circumstances, lead to corrosion. Submarine steel, by contrast, is completely resistant to prolonged contact with saltwater. Also, submarine steel is, on account of its ductility, extremely resistant to cracking, thereby further increasing its reliability.

我没有使用德国潜水艇的钢的表，但我有一块类似钢质的表。老实话一句，真的非常防刮。几乎碰碰吭吭都没有痕迹。真心希望来年百能停止黑钢了，都快全系黑钢。
