Titanium

It is commonly known that it is incredibly strong and light. This suggests that the use of it makes the creation of large, complicated watches simple. Grade 5 titanium alloy includes additions of 6% aluminum and 4% vanadium. These ingredients result in a titanium alloy that is more heat, corrosion, and scratch resistant and stronger. For grade 5, be prepared to pay more. Compared to stainless steel, it is 45% lighter and 30% stronger. A watch with this metal has the added benefit of rarely rusting. Nitric acid, which is uncommon in modern life, is the sole acid that the metal is incapable of withstanding.
