Abstract

The watch case includes at least one component element (2) made from martensitic stainless steel covered externally with a hard corrosion-resistant coating. A crystal (1) is attached to the component element (2) by a high-temperature weld, and the external coating (5) extends without discontinuity both over the component element (2) and the lateral walls of the crystal (1). <IMAGE>
