All Star Invicta Style!
While the 8 watch is unique, the dial does remind me of the Montblanc Grand Tourbillon Heures Mysterieuses timepiece. Not exactly the same of course, but thematically similar dials. They both have tourbillons as well. Can that large set diamond on the dial live next to a tourbillon? Will they steal attention from one another? Who knows. According to Cacheux, the watch will have a five day power reserve (via a single mainspring barrel) manually wound movement with the time and tourbillon. You will be able to see the movement through the caseback window on the back of the watch. There better be a few number 8s back there or I will be upset.
The case has no screws holding it together. In fact, it doesn't really have air in it either. This is the first watch I have heard of that has a vacuum sealed inner chamber. The caseback of the watch is vacuum sucked to the rest of the case - so don't try and pry it off. The 99.5% air-free space in the watch reduces friction caused by air - mostly via the escapement. According to Cartier, the removal of air from the case dramatically improves movement energy efficiency by almost completely removing energy that is lost due to air friction. Pretty cool. Though the complications mount when you think about the implications. Those being little things like how to seal the case, how to adjust the movement, and how an air-free space effects the movement. In short, Cartier had to patent a few things, remove all lubrication from the movement, and use some fancy new materials that are almost frictionless and don't need oil. Things more advanced than standard silicon.
