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.
