Citizen Super Titanium
Citizen Super Titanium is a true source of confusion ! “Super Titanium” is the name Citizen uses for most of its titanium models, but not all of its titanium models have the same scratch resistance. Lower cost models generally have scratch resistance at levels comparable to grade 5 titanium.
