Apple's unveiling event is both shrouded in mystery and heavy with speculation and it is a day away.

Since February, media outlets have spread the rumor of the Cupertino, Calif. tech giant was preparing to produce two iPhone 6 models, one with a 4.7-inch screen and another with a 5.5-inch screen. Now that Apple has announced an event for Tuesday, Sept. 9, at 10 a.m. PDT (1 p.m. ET), that "sketchy" report has seemed inevitable for some time.

According to the New York Times, the main attraction of Tuesday's event will be the iWatch, mainly for what it represents in Tim Cook's tenure as Apple's CEO. 30 years ago, Steve Jobs introduced the first ever Macintosh computer. Jobs later brought us the iPod, iPhone and the iPad and several reiterations of those devices.

The iWatch is the first iDevice that will truly be Cook's, an attendee of Apple's first unveiling event 30 years ago told the Times.

"I believe it's going to be historic," Tim Bajarin, a consumer technology analyst for Creative Strategies, said. "The design of this product is all Tim's fingerprints."

The iWatch is expected to pair with Apple's other mobile devices via Bluetooth. Users will be able to make calls, read text messages and even interact with their contacts on social media. One of its main features will be the Healthkit app, which will come with the iOS 8 update.

The iWatch will be able to read a user's blood pressure and heart rate and the Healthkit app will record such information and more. Like the original Mac was not the world's first computer, the iWatch is nothing new, but Apple is finally exciting people who have lost faith since Jobs' death.

"We think Apple's pipeline is finally going to satisfy those who have wondered if the company has any new products," Michael Yoshikami, CEO of Destination Wealth Management, told Reuters. "The stock price has been rallying as investors are beginning to believe that Tim Cook all along was telling the truth that there is an incredible pipeline of products."
