"Supertitan" hos Citizen er kalt for Duratect og det er ikke noe nytt.
"Gas hardening Duratect MRK
Duratect MRK is a technology that maintains titanium’s original properties of lightness and rust-resistance while hardening the surface of the material itself (as opposed to applying a coating to it). Two gases are injected into a special vacuum furnace and heat treatment applied to produce a hard layer about 20 to 30 microns thick on the surface of the titanium. Resistance to nicks is increased because the surface of the titanium material itself is made harder. Whether you’re hefting compressed air tanks out at sea or clambering up rocky mountain summits, Super Titanium™ will protect your watch from all the shocks that harsh environments bring."
