Stainless Steel
Stainless steel has long been used for fine watchmaking. It's renowned for it's durability
and corrosion resistance, which makes it the perfect material for a device that's worn all
day long. Apple takes stainless steel, then uses a specialized cold-forging process to make
it 80 percent harder, which helps to prevent nicks and scratches from reducing the allure of
Apple Watch. This same stainless steel is also used for the closures that enable Apple
Watch to fit so precisely. As for the Space Black Apple Watch, Apple adds a diamond-like
carbon layer to create a unique and durable finish.
