Images of an Apple Watch prototype inside a special security case have surfaced, showing pre-watchOS development software and a "Lisa Tester" app that shows how the finished springboard would look.
Apple tends to build prototype devices and disguise them in bulky cases to let testers use them without drawing unwanted eyes. The testing units are normally destroyed by Apple, but one has seemingly survived and images have been shared of the prototype running internal software.
The prototype in the images lacks a Digital Crown and runs internal testing software that existed pre-watchOS.
9to5Macfirst reported the images, which were shared by Twitter user @AppleDemoYT.
