A report from Matthew Panzarino of TechCrunch suggests that the Apple Watch has an additional port that has so far been unseen in public.
According to several sources the mystery port can be found in one of the grooves for where you connect a watch strap (see image). The port is said to be made up of six brass contacts.
Panzarino’s source explained that the port is currently used for diagnostic purposes only.
The TechCrunch piece goes on to deliberate how such a ‘hidden’ port could be used to facilitate a range of future accessories, such as ‘smart bands’ and external battery packs.
However, Jordan Kahn of 9to5Mac suggests that the port won’t make it into the final shipping product and is only in place for internal testing.
