Damn impressive photos. Thanks for posting!

Kind of cool to see how grimy nice patina looks up close

Great stuff, which bezel are the macro shot from DON or DNN?

 

It is a DNN from a 145.022-69, straight writing case back

 

Wonderful shots. What setup do you use?

 

Thanks, child's play with a Microscope Nikon SMZ745T

 

Fab, if you ever do requests, , could you compare the DNN with the DON please, would interested to see any differences in the fonts.

 

Sure, I'll try to post that beg of next week

 

Great thanks

 

The following pic presents bezel font of a DO90 mounted on a 105.003-65.
Will do the same for the 2 DNN versions, as well as a global comparison

 

This is about the best I can do for a macro.

 

Great photos, really appreciate it, need to save up for a microscope

 

Terrific reference points! Would love to see a snapshot of your setup.

 

Next is a nice 166.091, a diver from the 70ies:
