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.

Dekla uses the term "6Steel" to designate stainless steel cases which have been hardened using the Kolsterising® process.

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