The anticipation for the Apple Watch’s consumer roll-out this Friday is building with every moment that passes, and the wait for those who pre-ordered early has just gotten a little bit more tantalizing as Apple begins charging credit cards in advance of shipment. For many, the device is still listed as “processing items,” but for others, the status has advanced to “preparing for shipment,”and if you’re expecting to receive your Apple Watch by Friday, you may want to check the tracking and delivery status.

The Apple Watch has adorned the wrist of many celebrities as we close in on the consumer launch, and a number of high-profile figures have willfully sported variants of the higher-end Apple Watch Edition range. Some, such as Drake, Katy Perry, Pharrell Williams and J.J. Abrams, have had to settle for those currently up for pre-order, while others, such as designer Karl Lagerfeld and former rugby player Will Carling, have been treated to exclusive combinations that are not immediately available to purchase. Now, recording artist Beyoncé Knowles has got in on the act, and she has also been snapped rocking the gold link bracelet variant first demonstrated by Lagerfeld.

According to new estimates, the Apple Watch is likely to hit the 3 million sales mark in the first two weeks of it going on pre-order, generating a massive revenue of $2 billion. Reports are suggesting that Apple’s new wrist-strapped gadget could in fact be the company's most profitable product ever.

The Apple Watch has already managed to make quite a splash in the wearable market, and that's before consumers even have it in on their wrists. With an estimated over two million pre-order sales, it's almost certain that the first incarnation of the company's "most personal product yet" will become an instant hit with technologists. As with most products that ship from the Cupertino giant, the Apple Watch is a masterclass hybrid of cutting edge design and engineering and now, thanks to the intricate work of Martin Hajek, we can now get an exploded look at the internals of the precise timepiece, thanks to a set of custom created 3D renders.
