Earlier this week, a supposed set of schematics detailing Apple’s iWatch design and other details was seemingly leaked from China. The top-secret documents were said to have come from Quanta, Apple’s manufacturing partner for the iWatch and other iOS devices, though the authenticity of the documents was never confirmed — until now.

According to Jack March of A Tech Website, a thorough examination of the documents pictured in the leak reveals that they are, in fact, the genuine article. March took an in-depth look at them and compared them to real Quanta documents found on the company’s website through a simple Google search.

After some investigating, March determined that the leak is indeed genuine, meaning we can expect the iWatch Apple unveils during Tuesday’s event to closely resemble the design seen in the leak.
