Unizeit choose the 1.4404 steel (like 316L) produced by ThyssenKrupp® for its watch case.For the special-model, DLC technology (Diamond-Like Carbon Caoting) is employed to increase the abrasion resistance of the watch case. The parameter of abrasion resistance of Unizeit comes up to 1400HV. Unizeit has abandoned the production line work, but employed die forging technology in making sturdywatch case. And each case looks bright and clean as silk through independent grinding and polishing in high-tech processing center.

The sapphire lens is employed extensively for Unizeit watch. The sapphire bar, produced originally from Europe, is made into sapphire crystal surface through fine abrasive machining. In order to ensure the best readability in different brightness and from different angles, the sapphire crystal has conducted anti-dazzle treatment. And the coating firm is conducted in vacuum oven at the temperature of 280℃ (536 F). In this way, the visible ray refraction can be removed effectively. The dome shape is also known as sapphire crystal with big hook face. Because of grinding and polishing being very complicated, the rate of finished products, even we have well-developed manufacture technology today, is rather low. The more is an attitude that Unizeit makes the sapphire lens by means of this technology.
