“Stainless steel is both strong and beautiful. There's a reason it has long been used to
make fine watch cases. For Apple Watch, we start with an alloy of stainless steel known
for its strength and corrosion resistance. We then customize it through a series of alloying
and processing steps to make it even stronger. While in its molten state the composition of
the metal is tightly controlled to minimize impurities and ensure hardness. This is followed
by a specialized cold-forging process that helps to make the metal up to 80% harder and
less susceptible to nicks and scratches. The forgings are then machined in a 12-station
multi-axis milling machine, achieving highly-accurate uniformity across the case. It's
polished to a pristine polished finish. For the Space Black stainless steel, an additional
diamond-like carbon layer is added to achieve a durable finish and a brilliant appearance.
The bands receive the same careful consideration. Each Links bracelet is made from more
than 140 individual parts. The Milanese Loop is made from fine steel coils woven together
to create a flowing mesh with a fabric-like feel. With stainless steel, we've given a
traditional material a new expression.”

Featuring a polished stainless steel case and a sapphire crystal screen, the Apple Watch
oozes quality and timelessness.
It's the signature Apple Watch; a device that's instantly recognizable on the wrist of anyone
who wears it, and it comes in two colors: stainless steel and space black stainless steel.
With two sizes and 18 combinations of straps, there's a style and fit to suit everyone and
their needs.
Apple Watch is designed to be worn and used all day long, and to accomplish this feat,
Apple used 316L stainless steel. This material is 40% harder than regular stainless steel, so
it's less susceptible to nicks and scratches. To give the space black Apple Watch its color,
