Description: ETA turned to metal injection moulding for its range of SWATCH-IRONY watch cases because of cost savings compared with hot forming.

Composition: The cases, which follow the same basic design as the plastic SWATCH, are made in 316L stainless steel using a BASF moulding binder. Tolerances are generally ±0.05 mm, but must be maintained at ±0.025mm for the case holes. The cases are polished to provide a mirror finish.

ETA paid particular attention to health and safety issues, such as nickel allergy through release of nickel, when selecting the stainless steel material for the watch case.
