But not a wristwatch. I thought I'd share a link to the new rubidium fountain clock being developed by the USNO.

I call it quartz because such clocks use high accuracy quartz submodules as slaves. Evidently, they anticipate better (meaning stabler) performance than the NIST F1, which is the US standard for measuring time duration. Cool stuff for high accuracy geeks (or this one at least :-D ).
