Hanhart is the only watch brand in the world to use a certain kind of nickel-free stainless steel for its wrist chronograph cases. This steel has been treated using a special finishing process, making it extremely hard and therefore improving its scratch resistance by more than 10,000%. This means that watches that are put under a lot of stress will look as good as new even after years of wear! Additionally, this steel does not contain any nickel, so watch cases made from this material do not pose any known allergy risk. The use of this finishing process is patented for the watch- and jewellery making industry under the brand name HDSpro®.
The first Hanhart watches with cases made from this scratch-resistant stainless steel are due to be launched in 2012.
