Stainless steel is both strong and beautiful. There's a reason it has long been used to make fine watch cases.
不锈钢既坚固又富有美感。因此它长久以来一直被用于打造高级腕表。
For Apple Watch, we start with an alloy of stainless steel known for its strength and corrosion-resistance.
我们为Apple Watch精挑细选了一种强度高、耐腐蚀著称的不锈钢合金。
We then customize it through a series of alloying and processing steps to make it even stronger.
然后再通过一系列工艺，加以特别的冶炼和精煅，使其更为坚固。
While in its molten state the composition of the metal is tightly controlled to minimize impurities and ensure hardness.
当它处于熔融状态时，我们对其成分进行了极为严苛的管控，以最大可能的减少杂质，确保其硬度。
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.
随后再通过特殊的冷锻处理，使其硬度提升80%，并具备更出色的抗刮划能力。

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, mirror finish.
我们使用12刀座多轴铣床对锻件进行加工，使得表壳的每一处都精确到位，再经过抛光打磨，便形成了光洁纯净的镜面效果。
For the Space Black stainless steel, an additional diamond-like carbon layer is added to achieve a durable finish and a brilliant appearance.
而深空黑色不锈钢的表面，还附加了一层类钻碳，从而造就了与众不同的夺目外观。
The bands receive the same careful consideration.
表带的打造也同样独具匠心。
Each Links bracelet is made from more than 140 individual parts.
每一支链式表带都由超过140个独立组件构成。
The Milanese loop is made from fine steel coils woven together to create a flowing mesh with a fabric-like feel.
米兰尼斯表带则由精美的钢网编织而成，绕指柔滑，触感如丝。
With stainless steel, we've given a traditional material a new expression.
在我们手中，不锈钢这款传统的材质，焕发出了全然一新的风采。
