Micro solar system in your wrist.
When you are wearing the Midnight Planétarium Timepiece you'll forget the time, in fact you won't even care about it. Spend your days watching the small planets revolve around the tiny sun. This timepiece is very accurate, the Earth will take a year to revert back to its original position while the Saturn being the farthest will take 29.4 years. You can get one by personally contacting the maker through their website but you better be prepared to pay 300k US Dollars!
