步骤 4
Opening the Watch3 is a familiar—and relatively painless—procedure, featuring tri-point screws and a rubber gasket. These tri-points are tiny, but at least they're captive (hard to lose and easy to re-seal). While the back cover does feature a booby-trap sensor cable, its ample length makes it fairly benign. No traps were tripped in the making of this teardown.
  • Opening the Watch3 is a familiar—and relatively painless—procedure, featuring tri-point screws and a rubber gasket.

  • These tri-points are tiny, but at least they're captive (hard to lose and easy to re-seal).

  • While the back cover does feature a booby-trap sensor cable, its ample length makes it fairly benign. No traps were tripped in the making of this teardown.

  • The ECG sensor, heart rate sensors, and wireless charging coil are all packed tightly into the monolithic back case—but not this freewheeling little speaker, with its nifty gasket.

  • The optical biosensing is handled by the Texas Instruments AFE49I30.

  • Texas Instruments TLV9002 1 MHz Operational Amplifier

  • Modularity is neat! We approve. (Of the speaker, that is. We'll withhold approval of the other stuff until we find a way to extract it safely, which might take time.)
