DJ Questions 16200-16220-16234

[Brushpup]

I am trying to learn about these models and wondered if someone can elaborate. I'm after a DJ and want the Engine turned bezel usually seen on these. I also see this bezel on the 16234. Can someone tell me the years of manufacture on these models and what are the differences between these references if any? I have a reference pic for the aformentioned bezel type below. I would appreciate knowing anything more that anyone can provide.

Thanks so much,
Patrick

Very cool Dan thanks. When did they stop making the 16220? I've sinced picked up some info from Bullandvoka too, so I know now ffrom you both that I have been seeing sellers listing the wrong reference numbers and or watches.
