Here is the Motochron Watch. So far the best watch option I've seen of the 964/993 clock!

I just love it!!

I've bought it many years ago through a catalog for auto accessories, but never seen it again. I even contacted them in Germany to see if they had any more left, but hit a brick wall.....

It's a bit small for today's watch style, but works well when wearing a suit or any other wrist buttoned shirt.

 

Another one from Porsche Design:

 

Lets see a decent images of wrist watches that resembles the-993-vdo-clock.
