Apple’s rumored smartwatch probably won’t hit stores until late 2014 or even early next year, according to recent rumors, but it looks like the production on the alleged iWatch may have already started at the company’s mysterious sapphire glass factory in Arizona. A fresh batch of documents shared with 9to5Mac show Apple’s plans for a new sapphire component classified as “jewelry” in an official filing.

Today’s iWatch leak comes in the form of several official documents, with the first revealing Apple’s plan to increase production at its Arizona plant in an effort to “meet an aggressive go-live timeline of August 2014” in a letter sent to the U.S. Department of Commerce back in July. There’s also a more recent filing that lists a new sapphire component under the reference number 7116.20, potentially classifying it as an “article of jewelry.”

All signs seem to point to an iWatch, though that doesn’t necessarily mean we’ll get an official look at Apple’s rumored smartwatch anytime soon. It’s possible the company could unveil the wearable device this fall alongside other new products; some reports have pegged October as a possible debut month. Until then you can check out some of our favorite concept designs in the slideshow up top and stay tuned for more iWatch news and rumors as they hit.
