[time-nuts] Lothar Rohde's revolutionary 'portable' quartz-clock type: CFQ

[Adrian]

I just found this article about one of the earliest Rohde & Schwarz 
products, obviously a time-nuts related one:

Wow! 5E-8 (0.004 seconds per day) in the late 30's / early 40's, as by 
this article: http://www.mwjournal.com/Journal/article.asp?HH_ID=AR_6165 
seems a bit optimistic though.

Enjoy reading.
