Apple Watch reportedly features unannounced diagnostics port under strap connector
According to TechCrunch, the port features six brass contact dots and is positioned inside the bottom groove designed to accept Apple's aftermarket straps. Technically, a six-contact connector is similar to Apple's Lightning protocol, which currently uses six of its eight leads for charging and data transfer.
It is not clear if the port will be included when Apple Watch hits store shelves, but sources inside Apple have confirmed its existence on what the publication believes are shipping versions of the device.
A source said the port currently plays a role in diagnostics, but points out that it could be used as a connection point for accessories in the future. TechCrunch speculates that such a data port could be used as a means to facilitate feature expansion, perhaps "smart bands" that extend battery life or tack on GPS and other sensing capabilities.
