An Apple Watch Series 6 CPU tester

Seen on eBay, something a bit unusual: an S6 SiP tester. That is, a device for testing the main chip of an Apple Watch Series 6.

It is listed for $240, and you can see a barrel connector for power—likely a Lightning connector—and an LED. The seller mentions that the SiP is not included. For reference, a SiP (System in Package) is the term used when a chip integrates all functions into a single component, including sensors.
