Datejust 1603- two from c '68

[Tbonewalk]

I just got another DJ. I have two. I didn't realize they are both 1603s. They are both also from approx 1968. This last purchase, it has a gold bezel. It looks amazingly shiny and I almost question it's originality. I suspect the hands were changed, because they have some lume. And the two-tone bracelet is dated considerably later. Crystal was changed too. So it's up to snuff. It looks great and the price was too. So I feel safe with it. But I wonder if it was "touched up" and if it left the factory this way. They both run very very well with great reserve and great accuracy. So I like them both a great deal.

But it struck me, and I throw this out to you...

Would the 1603 be offered with a gold bezel as well as a SS? Was that configuration an option?

I'm showing both here.

I'm also interested in the chronology of the DJ. When did the 1603 come along, when did it end and replaced by which model. When did the 1601 end; was it offered concurrently with the 1603?

I take it that then, like now I suppose, there were several different models or editions of the DJ, with characteristics and qualities unique to each. Any info is appreciated.

thank you!
