It's always an interesting feeling to look at the pictures, think to myself that this level of mechanical precision could easily be achieved today, then realise it would've been made between 160-230 years ago.

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

    I think the thought was the other direction - it wouldn't be impressive today, but for its time it is impressive.

      At present what they are doing at the bleeding edge of mechanical watch making is very impressive: https://www.thenakedwatchmaker.com/making-uvliga https://www.thenakedwatchmaker.com/making-uvliga Yes, that's watch parts from litho, as in how we make processors...

    Alright so go do it, then.

  Clickspring's recent video goes into some detail on at least one of the clever tools used to achieve this incredible precision: https://www.youtube.com/watch?v=X4xy7TFkxsg https://www.youtube.com/watch?v=X4xy7TFkxsg

    Beautiful. And I'll use that wobble stick idea, albeit perhaps on a larger scale.

      It's basically a primitive dial indicator.

  this piece in particular, considering it has a thermometer complication.

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: https://www.youtube.com/watch?v=kULgoiQ8EXQ https://www.youtube.com/watch?v=kULgoiQ8EXQ The large escape wheel is used for locking, and the small escape wheel provides the impulse.
