New designs are pretty much all digital (for better or for worse). If a spaceship needs a backup timepiece, it will just carry a second digital clock. If a spaceship needs a mechanical lockout, it will just do it with microswitches, solenoids, and digital logic.
I suspect I just reinvented nanotechnology. For some reason, this watch article makes it feel much more real.
There seems lots of cool applications for that, apparently also Timex is bringing out a watch which uses the technology in some way ( http://www.ablogtowatch.com/timex-silmach-watch-movements-me... ).
Also MEMS is used in DLP projectors, where lots of tiny little mirrors can be moved which seems rather amazing.
From the Wikipedia article, one might even say this is a MEMS watch. MEMS describes devices up to 1mm having components up to 100 microns. This watch has parts as thin as 20 microns, so although it is overall larger than MEMS, its components encroach on MEMS territory.
