A material to withstand any extreme conditions
 

904L grade stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids. While its unique hardness allows it to withstand extreme conditions, it also requires special machinery and production processes in order to be shaped. Visually, 904L grade steel has a beautifully high polish and ages exquisitely well.
 

Select BALL timepieces are now built using 904L steel. Though every timepiece is made to handle harsh conditions, the implementation of 904L stainless steel only fortifies our strength and reliability.
