So... there's none of whatever he calls "craftsmanship" (engineering plus whiny nostalgia) in making a cesium clock the size of a watch? Useless twit...
From the perspective of a high end mechanical wrist watch, then really no, there isn't.
The final assembly and adjustment of a wristwatch sized
tourbillon, or many similar contraptions inside mechanical watches, cannot in any way, shape or form be automated nor done assembly line fashion by unskilled labor.
Even when starting with micro-CNC fabricated parts made to the highest possible precision, it still takes several
days worth of actual adjustment and tweaking time by a skilled watchmaker to assemble and calibrate a
*reliably running* tourbillon. Actual calendar time used is much longer than that, as each 'tweak' frequently needs one or more prolonged test periods, before the next assembly step can commence.
Even getting the training and experience needed to be able to do the job at all takes many years of watchmaker experience, potentially decades even. So the job cannot be outsourced to cheap, low skilled workers in a third world country.
I am not aware of anything in any atomic clock, which requires the same level of skill on part of the people fabricating them?

Conversely, you could make a killing in the world of luxury watches, if you know how to build a machine, which can automate tourbillon assembly/calibration and many similar processes.

Edit: Added emphasis to 'reliably running', as that is the key here.
