Well I found a twin to Bob's example of the Rose Gold Black Dial Navigator. https://mybulova.com/watches/1944-navigator-9977. So no doubt this was a factory model. The case is rose gold with a stainless steel back.The first number of the serial number is illegible. Based on the date code Triangle on the movement it is possible it to be a 5 but it does kind of look like it could be a 4 so I am going with 1944. The dial is black with copper colored printed hour markers and the hands are yellow gold. Really a gorgeous watch and I am surprised we don't see more of this combination from Bulova.

I have just purchased this exact model.
Keeps perfect time. I need to find the original hands. As well as a rose gold bracelet.
