The Apple Watch isn't an iPhone-like revenue generator, but is part of the company's growing Other Products segment.
Apple is also working on two new iPad Pro models with slimmer bezels and facial recognition along with a new low-priced MacBook laptop and a Mac mini desktop geared toward professionals, Bloomberg News has reported.
Judging by Apple's past actions, analysts expect the company will begin selling some of the new models by the end of September.
The tech titan released an invitation to members of the press Thursday morning inviting them to "Gather Round" the Steve Jobs Theater in Cupertino, Calif. on september 12.
Apple's event comes a month after smartphone leader Samsung unveiled its latest flagship handset, the Galaxy Note 9. They show an edge-to-edge display and a new watch face that includes more information than those of current models.
Based on the invite that went out, it appears the iPhone will be the primary focus of the event.
Apple's clever 3D Touch feature has seen mixed success since its introduction in 2015 with the iPhone 6s.
Besides the new iPhones, Apple might also use the event to announce new Series 4 Apple Watches. From an Apple Watch with more screen real estate to the debut of the long-awaited AirPower Mat facilitating wireless charging, the California company may drop some non-iPhone surprises.
In regards to other details, it's claimed that most are yet to be verified.
