Fresh off their success raising over $1 million on crowdfunding campaigns, ERA's Prometheus tourbillon watch is now available for pre-order. The ERA Prometheus--the #1 mechanical watch project of all time on Indiegogo--is a luxury, single-axis tourbillon with a skeleton 20 jewel movement, 24 hour GMT timer, day/night indicator and 35 hour power reserve housed in an exhibition case made of stainless or titanium that attaches to your wrist with a leather band or steel bracelet. Even better? You can strap this tourbillon on your wrist for a fraction of the cost of other options.
