       | achieved today, then realise it would've been made between
       | 160-230 years ago.

         | Right? Like this isn't even that much impressive, considering.

           | impressive today, but for its time it _is_ impressive.

             | mechanical watch making is very impressive:

             | Yes, that's watch parts from litho, as in how we make
             | processors...

           | perhaps on a larger scale.

       | This post is about a specific watch that has a duplex escapement,
       | but doesn't really go into the workings of the escapement.

       | This video has a good example showing how it works:

       | 
       | The large escape wheel is used for locking, and the small escape
       | wheel provides the impulse.
