  • Time to dig into that second electrode—the all-new digital crown. We pull off some pieces and quickly find the fun parts.

  • Grab your magnifying glass—we're entering micro-world.

  • The internal golden cylinder has micro scratches on it, allowing an optical encoder (the little black box on the ribbon cable) to track its rotation.

  • The springy bracket behind the cylinder likely conducts the electrical signal from your finger through to the watch, completing the ECG circuit.

  • The tiny switch behind that spring acts as the crown's mechanical button. Plus, there's a nice gasket on the exterior crown shaft for ingress proofing.

是时候深挖第二个电极——全新的数字表冠。我们拆下一些部件来快速找到这有趣的部分。

拿好你的放大镜 - 我们正在进入微观世界。

内部金色圆柱体上有微小划痕,允许光学编码器(带状电缆上的小黑盒)跟踪其旋转。

圆柱后面的弹性支架可能会将手指的电信号传导至手表,完成 ECG 电路。

那个弹簧后面的小开关充当了表冠的机械按钮。此外,外部冠轴上还有一个很好的垫圈,可以防止外物的侵入。
