Like a technology rock star, Apple CEO Tim Cook is currently on a world tour promoting the Apple Watch before its official unveiling March 9 at a special event to be held at the Yerba Buena Center in San Francisco.

Cook ventured this week to the United Kingdom where he made an unannounced visit to the Covent Station Apple Store at The Piazza in London on Friday, reports The Telegraph.

He is already wearing an Apple Watch; the Sport edition with a white wristband. He couldn't imagine living without it, he said.

"I'm now so used to getting all my notifications and all my messages," he told The Telegraph. "It's so incredible just to do this."

Cook believes that consumers will initially buy the Apple Watch as a fashion statement, and the company has worked hard to make the wearable aesthetically pleasing. The CEO said that consumers will soon discover the watch is much more; it is remarkably accurate-able to keep time within 50 milliseconds of variation-and he expects an "explosion of new apps" for the smartwatch that will drive integrations with more of the other devices that people use daily.

The smartwatch is touted to have many uses. For example, it's possible, according to Cook, for the Apple Watch to replace a person's car keys or key fob. The watch's ability to do so reinforces that Apple is making its mark in the automotive market.

Another major application: the Apple Watch can replace a credit card using Apple Pay. The system will be safer than the plastic credit cards used in the U.S., Cook promises. He added that Apple respects their customer's privacy and will not collect data on what users are buying, where they are buying and how much they are spending.

When users experience the Apple Watch's full potential, Cook says, they will understand how different it is from a traditional watch.

"This will be just like the iPhone: people wanted it and bought for a particular reason, perhaps for browsing, but then found out that they loved it for all sorts of other reasons," he said.

The possibilities of integrating other devices with the Apple Watch could be endless. Appliance makers, smart home platforms, automakers, public transit corporations, airlines and more might begin to see the benefits of setting up integration with a device worn by consumers.

It will be interesting to see what, if any, significant impact the Apple Watch has on our everyday lives once it is released in April.
