They're shockingly ugly (and expensive) beasts, but you can now get atomic wristwatches. (Actual atomic watches, not the "atomic" kind that simply receives the radio time signal.)

Well the pocket watch isn't that bad looking......

Oh my.

The description of their "high-pressure liquid chromatography" technique sounds an awful lot like how one would enrich uranium (you know, as one does.) Did they accidentally invent a better uranium enrichment process (or independently reinvent a classified one?) Or is there some difference between {C60, N@C60} and {U235, U238} that makes using HPLC to enrich it impossible?

For the initial time sync, apparently. I guess if you have an atomic clock on your wrist, you want the time displayed to actually be correct.

That’s impressively small. I had a rubidium frequency standard which was several orders of magnitude larger I.e medium sized hardback book. This used a cesium beam approach. Haven’t seen one of them less than a 2U rack before.

Dubious as to the point though as the sources all have a finite operational life, usually a decade or so.

Nowadays wrist watches rarely have a point besides showing off your wealth.

This is true. I don't actually own one because it is of no use to me.
