Hardened Watch Cases



These Sinn 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.
