1200 HV
HARDERNED STEEL
The case and bracelet of the Marinor are made out of 316L (Marine-Grade) Stainless Steel in a brushed finish, an obvious choice for dive watches due to its corrosion resistance and high durability. However, the Marinor undergoes a laborious hardening treatment, rendering the watch virtually scratch-proof.
