Bremont Stainless Steel watch cases are treated for hardness with B-EBE2000 technology. During this special stage in the case production the metal is heat-treated and defused with carbon, then bombarded with electrons. The process dramatically increases the hardness and scratch resistance of the stainless steel. On the Vickers’ scale of hardness, for example, B-EBE2000 produces a watch case with a value of 2000Hv - approximately seven times that of the normal stainless steel used for watch cases.
