Earth shattering news for GNSS, commercial availability of Chip ScaleAtomic Clock (CSAC)

How sensitive are these CSACs to other environmental variables? What about
shock, or position? Are they robust enough to be used in wris****ches and
portable timepieces (disregarding cost)?

Which reminds me: why are there no wris****ches that use GPS just for a time
reference, without the geolocation functions? Or are there? Seems like there'd
be a market for such watches to replace "radio-controlled" watches depending
on WWVB and the like, if the price isn't too high. They wouldn't need a CSAC,
although that would be a nice bonus.

Radio controlled watches do the same thing more cheaply,
and work in most of the inahabited world,
at a much lower power consumption.

There would be at best a small niche market for such a thing,
