Nivada 'Newman Subdials' valjoux 7765

So, I like this design. But, I cannot find any info about these.

Nivada, Dugena, and LeJour used this case and dial.
Singer made these dials.

Some photos I have found from the web.
In the case of Nivada there's a model called ChronoSport, but not sure if that is historically correct.
The reference nr found on the case back is 500-1.

- 'Paul Newman' dial by Singer
- 37mm steel case
- 18mm lugs
- rotating bezel
- manual wound Valjoux 7765 movement
- screw down crown
- 1980s
- plastic crystal

Thank you for this information and links @Vitezi

So, I received mine today. Of course, I had to take some photos and a video 😀
NOS, but was serviced just before sent to me.

And now Nivada revived this old classic. Not blue, but the black with “big eyes”.

So, I got the chance to shoot this new Chronosport next to my vintage.
