A new report from TechCrunch notes that the upcoming Apple Watch has a port that Apple has yet to show off hidden in one of the two slots where the Watch’s straps connect to its case. The report brings up the possibility of using it to facilitate “smart straps” and other Apple Watch accessories, but 9to5Mac has learned from sources that the port, which is actually a Lightning port being used for testing, will not be included on the product shipping to customers.

The port is currently being used to connect to the Watch for development purposes, but TechCrunch speculated it could be used to bring “smart straps” to the device in the future:

The reason I ask is that the Apple Watch has a port that the company has yet to show off. It’s being used for diagnostics and direct access to the Watch operating system, but it’s feasible that could be used to connect accessories in the future.

A similar platform was announced as part of the recently introduced Pebble Time smart watch to allow bands to interact with the watch’s OS and add additional sensors to the device.

The report from TechCrunch also notes that Apple snuck in its usual “Assembled in China – Designed by Apple in California” marking inside the other strap slot.
