Apple Watch Series 7 Lacks Hidden Diagnostic Port, Likely Uses Wireless Data Transfer Instead

Last month, FCC filings revealed that Apple Watch Series 7 models are equipped with a new module that enables 60.5GHz wireless data transfer. This module is not advertised on Apple's website and is likely for Apple's internal use only.

The lack of a diagnostic port on Apple Watch Series 7 models likely explains the addition of the 60.5GHz wireless data transfer module. FCC filings indicated that the module is only activated when the Apple Watch is placed on a proprietary magnetic dock with a corresponding 60.5GHz module, so it sounds like Apple might use this dock to perform diagnostics or restore watchOS wirelessly on Series 7 models.

It's also worth noting that Series 7 models feature IP6X-rated dust resistance, so perhaps the diagnostic port's removal helped with that to some degree.

Apple Watch Series 7 models will begin arriving to customers and launch in stores this Friday, October 15. Key features include larger displays with 41mm and 45mm case sizes, enhanced durability with IP6X-rated dust resistance, up to 33% faster charging with an included USB-C fast charging cable, and new aluminum colors.
