Having a watch that can set itself according to its location is great. So is having a watch with a mechanical movement. With the VCXO One Magic Button Watch, you get both. Powered by an automatic mechanical movement with a 5-day power reserve, this unique timepiece features the aforementioned button on its side at 9 O'clock that activates a GPS module, figuring out the current local time and setting into motion a small motor that sets the time for you. As a result, there's no crown on the other side of the 46mm watch — just a button that winds the movement and gives you more juice. Magic, indeed.
