Ok. I have an AD that has both models new (NOS obviously). I believe both modules are the same.
1659 and 1289.
I've had a 6900 before and I loved it. It is an icon and ubiquitous.
The 9052 has a cool movable lug/strap system. My wrist is 6.5 inches.
Price is the same. I know - get both.
I'd like some input please. Thanks.
Oh, and both say made in China. Was that normal back then? Mid 90's?
