Hardened Watch Cases



These Sinn, Dekla, and Hanhart watches feature cases that have been hardened to offer extreme protection against scratches, wear and dings.

  • Sinn uses the term "Tegimented" to designate their watches with hardened cases, which may be made from stainless steel, submarine steel or titanium.

  • Hanhart uses a process called HDSPro® which makes the stainless steel up to 100 times more scratch resistant than standard stainless steel.

  • And Dekla hardens their cases to 1,300 Hv (six times the hardness of a standard watch case) using their 6Steel process.
