There were hundreds of watch makers / assemblers that used electric and electronic movements in the 1960s and 1970s. The list above only represents those makes where I own an example. If you have some other make that is not listed and you want some help, advice or just want to show me, please do get in touch using the email link on the home page...I'm always interested in seeing other makes of electric watches!
Caravelle
Caravelle was a brand owned by Bulova.
The 12 OUCD movement is of the
Fixed Coil, Transistor Controlled Balance variety and is
the same as the Citizen 4830. Both movements are related to
the
ESA Dynotrons (9157, 9158). In fact, you can clearly see the "LIC. ATO" on the
12 OUCD plate below; this acknowledges
their technology inheritance with the Dynotrons.
