It draws quite a lot of power. From what I remember, the lipo battery required for 16hrs w/ no display would be the same size as the already chunky module itself, requiring wristband integration. Better to have a quartz oven and fire up the CSAC only once per hour as a reference, still yielding one factor of 10 in precision.
All in all it's better suited for a nice pocket watch with a 10MHz out connector. Any takers at 15k$+?
Hah. Admittedly I didn't look up the power consumption. I came across these modules a few years ago randomly and seeing this article reminded me of them.
I wasn't seriously suggesting it's a practical answer by any means =)
