New project by Central Standard Timing released at CES (has already reached their fundraising goal):

The CST-01 is assembled by laminating thin, flexible components into a 0.5mm pocket etched into a single piece of flexible stainless steel.  In order to make the watch as thin and minimal as possible, there are no buttons or knobs on the watch itself.  Charging and setting the time is done on the included base station, and for those outside the US who prefer a 24 hour time format, this is also user selectable from the base station.
