Looking for pre 1959 example. None in our database. Rantff remarks "1959 to 1963" at http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Bulova_10BZAC.  NOVA also lists start date as 1950, but her two 23 Jewel examples are from 1959  (Beau Brumme)l and 1963 (Regatta).  I think the 1950 estimate is too early. 

Edited to start date of 1959 w/ this caveat.  End date changed from blank to 1963.
