It is no secret that Apple products support a wave of features but are inaccessible to users for some reason. On this occasion, the Apple Watch Series 7 supports 60.5GHz wireless data transfers thanks to a new module, but you cannot advantage of it.

According to FCC filings spotted by MacRumors, the 60.5GHz module can only be activated when the Apple Watch Series 7 is placed on a proprietary magnetic dock that also features a 60.5GHz module. At this time, there are no such docks available for customers, which would explain why the data transfer feature is not usable either. There is also no word if Apple will allow this data transfer to happen through a future software update or if the company starts selling the dock separately.
