Omega Seamaster Cermet ”Black Tulip” Ladies NOS

Hello!

I just picked up one of my grail watches:
• Omega Seamaster Cermet ”Black Tulip” Ladies
• Reference: 1960249
• Size: 26x28 mm
• Year: 1982 (?)

Note that it is the smaller ladies sized version. Doing some research about this is that only about 700-800 of these watches were ever made. Maybe someone can help me out with a few additional questions I have about it?

Clearly it is New Old Stock and never previously worn. However, what is confusing me a little after comparing to images of this watch online is:
1. Why is the crown not the classic Omega stamped silver crown?
2. Why is there not a seconds hand? And why are the hands not thin like the ones I found online?
3. I found that some of these watches have a white date wheel while other have a black date wheel, any reason for this?
4. How do I find out the exact year of this watch?

I attached some images I have taken and what I found online.

My thinking is that the watch was never ”finished” and actually never sold to a customer? But I have no idea, please give some input if you have any!

Neat watch but curious, esp with the non crown and other changes.

Wear it and enjoy! Go hunting for a crown to get it back to spec.
