Apple Watch Sport
“Aluminium is naturally strong and lightweight; it's the ideal material for Apple Watch
Sport. Our engineers have custom-designed a new alloy. It is 60% stronger than standard
alloys, but just as light. This requires precision alloying. Raw aluminium of exceptional
purity is first heated to a molten state. Tightly controlled amounts of magnesium and zinc
are then added. As these elements bind together, they form a protective compound that
strengthens the metal. That alloy is then poured, jet-cooled and cast. A high-temperate
treatment minimises uneven chemistry and billets and ensures proper grain structure.
Next, a finely-tuned extrusion process creates a uniform surface free of defects. After being
meticulously formed, each case is machined, buffed and then textured with microscopic
zirconia beads to achieve a consistent satin finish. Finally, anodising creates a hard, clear
outer-layer that helps protect against dings and scratches. We believe this aluminium alloy
sets a new standard; both in the way it performs and the way it looks.”
Jony Ive, describing the manufacturing process for creating the durable Apple Watch Sport
case.
It's likely to be the most popular model of Apple Watch, with the most affordable price and
a range of colorful bands to suit all tastes.
We're talking about the Apple Watch Sport, of course. It's made from a custom 7000 Series
alloy that combines aluminium and zinc to create a materiel that's 60% stronger than
typical aluminium, while being 30% lighter than the stainless steel model; and because the
aluminium has a brushed look to it, you won't need to repetitively polish its surface.
As with all Apple Watch models the Sport is water resistant and splash-proof, meaning
gym sweat and everyday splashes should be okay, but don't take the Sport swimming or
for a shower. However, unlike the Apple Watch and Apple Watch Edition, the Sport
features a Ion-X glass screen, instead of a sapphire screen. It's still incredibly strong and
light, but unlike sapphire, which is the second strongest transparent material after
